The 3 side will be higher, no? But how do we find the missing side of the right angle triangle? c^2 = a^2 + b^2 would give the missing height, but a different answer depending on if the 3m side is used or the 4m side is used. To solve this, all i would need is the angles of the right angle...

Homework Statement A 5m long uniform beam AC with mass of 600kg is being lifted from the ring at B by two chains (AB, 3m long and CB, 4m long). Determine the tension in chain AB and CB when the beam is clear of the ground. Homework Equations The Attempt at a Solution I tried...

I think I've got it. With this formula T sin(theta) = W/2 i can get the angle cause i know the max tension, but then how do i get the length of the chain from that?

Homework Statement Hi guys, really stuck on this one. A 1000N black is to be lifted using a chain sling (as shown). If the tension in the chain sling is not to exceed 1300N, find the shortest sling ABC that can be used. A is the most left point, B is the most right point and C is the top...

I might give that a go bud. Thanks!

Homework Statement The human sneeze can reach speeds of 150km/hr. Calculate the gauge pressure in the lungs required to generate a flow with this speed at atmospheric pressure. Assume the density of the air is constant at 1.3 kg/m^3. Homework Equations The Attempt at a Solution I...

My apologies, p1 and p2 are the density. I think they're called rho?

Ohhh, so I should use the formula p1*v1*A1 = p2*v2*A2?Thanks bud!

Homework Statement A scientist attempts to model the flow of blood through an artery using a hollow pipe of diameter 1.8cm. A fluid density 1060kg/m^3 is used to simulate blood in the pipe. Viscous effects can be considered to be negligible. TO study a blockage in an artery, the...

... damn.Hahhaha thanks man. I can't believe i never realized that.

Homework Statement Hi guys. X-ray energies are commonly given i nunits of "electron volts". 1 eV is the energy that an electron would have after being accelerated across a potential different of 1V and is equivalent to 1.601 *10^-19 In an x-ray machine an electron that is about to hit an...

Homework Statement A)You have a tank containing 750 mL of water and a heater outputting a max of 400 W. If you start with the water at 25 degrees, how long till it reaches boiling point? B) How much heat must be input to melt 1 gram of ice? What is the volume of meltwater does this produce...

I stuffed up the arithmetic. Answer should be -1800. Is that right? Seems big for acceleration.

Homework Statement Steel ball with a mass 17 grams, is launched at a speed of 6 m/s, into someones eye. The ball comes to a rest over a distance of 1mm. A) What is the average acceleration experienced by the ball to stop it? B) What is the deaccelerating force that must be exerted on...

Hahaha definitely asking. I'm nearly positive it would be 5v but I want to check if I'm correct.
