please help! i don't know how to solve da problem please help: Two ropes are used to carry a load of weight 400N. The ropes are 40 degrees to the horizontal. Show that the force applied by each rope is to the container is abou 300N.

I have problem figuring out the reflection of a pulse on a rope with a fixed point. Do you know some websites to find animations about it?

Hello I often go climbing. When I went with a guide recently he told me that you should be especially carefull when climbing when you only have a small length of rope paid out arguing that because the rope is so short at this point it must take a large shock under a fall. Conversley, if you...

How would I calculate this A horizontal force of 809 N is needed to drag a crate across a horizontal floor with a constant speed. Pete drags the crate using a rope held at an angle of 33°. What force does Pete exert on the rope?

How would I find the tension of a rope that is attached to an object being swung around in a circle? If I find the centripetal force would that be the same thing as the tension?

An 80 kg person standing on a 20 kg plateform is suspended by a rope passing over a stationary pulley that is free to rotate. The other end of the rope is held by the person. The masses of the rope and pulley are negligible. You may use g=10 m/s/s. Assume that friction is negligible and the...

>> A taut rope has a mass of 0.165 kg and a length of 3.75 m. What power must be supplied to the rope to generate sinusoidal waves having an amplitude of 0.120 m and a wavelength of 0.480 m, traveling with a speed of 30.5 m/s? I'm not really sure how to start this. I have an equation of...

This question looks really simple, but I'm having surprising difficulty with it. A hemisperical sign 1 metre in diameter and of uniform mass density is supported by two ropes, as shown in the diagram. What fraction of the sign's weight is supported by each rope? I am having trouble...

One question related to Newton's third law, v t p u o u o It is a rope with a wheel,v. If 50N is applied from u pulling towards the ground, what's...

A refrigerator is approximately a uniform parallelepiped h = 7 ft tall, w = 3 ft wide, and d = 2 ft deep. It sits upright on a truck with its 3 ft dimension in the direction of travel. Assume that the refrigerator cannot slide on the truck and that its mass is 100 kg. For the first three parts...

I need help with this question (the picture is attached): A foot, mass of 4 kg, is suspended by a pulley system. The net traction force needs to pull straight out on the leg. What is the proper angle theta for the upper rope? I know that the system is frictionless so the tension in the...

Consider a rope with length l and mass per unit length (lambda), hanging vertically. Let y refer to the height of a point P above the bottom of the rope. What is the tension at point P in the rope? Thanks a lot ppl... I know the answer should include y but not sure in what way...

How do I find the direction and magnitude of the force exerted on the massive rope by the ceiling? And what is the tension at point P in the rope? Thanks in advance,

If you take the wheel as your system, would the tension in the red rope be 10 lbs also? pic attached thanks

I am given the information: A water-skier is pulled behind a motorboat with a rope 8m long. As she is approaching a ramp, she pulls herself 2m to the side of the path of the boat. It creates an angle of 14.5 degrees. I am asked: 1.) how much of the tow rope force is in the forward direction...

Hi, I have tried to solve this puzzle: If we had a round meadow and a cow tied with a rope on the edge of that meadow. Hw long should be a rope if we wanted to let the cow eat a half of that meadow? I have tried to solve this puzzle time ago and now it attracted me again. Does anyone know how...

Desperate for a help with tension in rope! Two blocks are connected by a cable via a pulley which are massless and frictionless. Given the following: m1 = 300.0 kg, m2 = 100.0 kg, theta=40degrees, uk=.350 ,what is the tension in the cable? So have figured out the acceleration to be .304m/s...

Rope, Pulleys... and Lots of Tension! hey, For the following problem a picture is really needed so I tried drawing one on Paint and uploading a bitmap file ut it said that it was too large... A 7 kg monkey climbs up a massless rope that runs over a frictionless tree limb and back down to...

WOULD SOME1 HELP ME WITH THIS ANNOYING PROBLEM I CANT SOLVE : a cat is wrapped around a fixed cylinder .theres friction between the rope and da cylinder with a coefficient of friction (mu) , the angle covered by the rope on the cylinder is (pi)/3 .assume a really thin rope. A cat is pulling on...

A nylon rope of length 80 ft. is under a tension of 3000 lb. The total weight of this rope is 6 lb. If a wave pulse starts at one end of this rope, how long does it take to reach the other end?

Here is another one of these spool problems: A large spool of rope stands on the ground with the end of the rope lying on the top edge of the spool. A person grabs the end of the rope and walks a distance L, holding onto it. The spool rolls behind the person without slipping. (a) What length of...

How long does it take typical inelastic rope to stop a person in freefall? I'm taking a gun-safety course and the instructor claims that for a 200lb person falling 1 meter out of a tree stand before their safety harness halts their fall, it applies a force of 1700 pounds to the body. I feel...

The transverse displacement of an harmonic wave on a stretched rope is y = 0.04 cos(2.5 t - 3.3 x), where x and y are in meters and t is in seconds. A 5 meter length of this rope has a mass of 1.5 kg. a) What is the tension in the rope? b) At time t = 0, consider a 1/2 wavelength long...

A 4 kg mass is connected by a light cord to a 3 kg mass on a smooth surface.The cord is around a frictionless axle and has a moment of inertia of .5 kg*m^2 and a radius of .3m. Assuming that the cord does not slip arount the axle, a) what is the acceleration of the two masses b)what are...

http://abs-5.me.washington.edu/me230/hw_solut.pdf Could someone please look at this website. Specifically problem 14-54. Why is a force on the box 3F? I don't understand why it is 3F. I only see two ropes going from the box.

Can anyone help me on two problems of my hw? 1) A tow rope is used to pull a 1050-kg along a level road, initially accelerating it from rest at 1.50m/s^2 for a duration of 12.0seconds. Calculate the magnitude of the tension force in the rope during this acceleration.(ignore friction in the...

Newton's laws? there is an athlete climbing a rope in gym class. he gets to a point halfway up the rope and is stationary. someone puts a bag of sand that is equal in weight to the athlete. they are both static and then the athlete starts to climb the rope, slowing and speeding up at random...

This is the first time I've posted here. I am having a problem with an assigned problem. I know the policy here is to not give out answers, and I'm not looking for that. I just need a starting point. Here's the problem: A 5.00 kg block is pulled along a horizontal frictionless floor by a...

Okay, a box of mass m is dragged across a floor by pulling a rope attached to the box and inclined at an angle @ above the horizontal. given that the coefficient of static friction is 0.05, what minimum force mag is required from the rope to start the crate moving? When it says it is...
