Homework Statement Collar A can slide on a frictionless vertical rod and is attached as shown to a spring. The constant of the spring is 4lb/in., and the spring is unstretched when h=12in. Knowing that the system is in equilibrium when h=16in., determine the weight of the collar. Home-made...

Homework Statement A spring has a force sensor attached to it and is pulled at increasing distances from rest. A reading is recorded on the force sensor and the data is plotted below. Plot data on Excel x (m) Force (n) .005 1.9 .010 2.5 .020 3.4 .030...

Not really something I am working on at all, but a while ago I had heard that engineers for some of the race teams, mainly NASCAR have developed and put into use and compression spring that has a uniform force of the entire distance of deformation. To put it better, you have a suspension...

I need to calculate the spring force required to make a back pressure regulator for fluid control the back pressure must exceed 3bar to open the ball valve the flow rate is 82mls/per min. the bore dia of the inlet is 2 mm dia. any help greatly appreciated

What happens when the NET force on a massless body is 0. I mean what will be the acceleration , if any? Also if we pull a massless spring, from one side with a force F1 and from the other side a force F2, what will be the spring force?

A 2.00-kg block is pushed against a spring with negligible mass and force constant k = 400 N/m, compressing it 0.220 m. When the block is released, it moves along a frictionless, horizontal surface and then up a frictionless incline with slope of 37 degrees. a) What is the speed of the block...

Homework Statement When a 75 gram mass is suspended from a vertical spring, the spring is stretched from a length of 4.0 cm to a length of 7.0 cm. If the mass is then pulled downward an additional 10.0 cm, what is the total work done against the spring force?Homework Equations U=mgh (Don't need...

Homework Statement A light spring with force constant 3.85 N/m is compressed by 8.00 cm as it is held between a 0.250-kg block on the left and a 0.500-kg block on the right, both resting on a horizontal surface. The spring exerts a force on each block, tending to push them apart. The blocks...

Homework Statement Consider a spring with spring constant k = 8.42 N/m with an unstretched length of 0.250 m. How much work do you do on the spring in stretching it from a length of L1 = 0.450 m to a length of L2 = 0.559 m? Homework Equations F= kx W=(1/2) kx^2 The Attempt at a...

Homework Statement A 6.90 mass hanging from a spring scale is slowly lowered onto a vertical spring, as shown in the figure. What does the spring scale read just before the mass touches the lower spring? --> I calculated this to be F= 67.6 N just using m*g. The second question is: The...

Homework Statement The ball launcher in a pinball machine has a spring that has a force constant of 1.2 N/cm. The surface on which the ball moves is inclined at 10° with respect to the horizontal. If the spring is initially compressed 5 cm, find the launching speed of a .1 kg ball when the...

A 86.3g ball is dropped from a height of 52.3cm above a spring of negligible mass. The ball compresses the spring to a maximum displacement of 4.9296 cm. The acceleration of gravity is 9.8m/s^2. Calculate the spring force constant k. answer in units of N/m.

We know that atoms are held together by atomic bonds and when one atom is moved away from the one it's bonded to, there is a restorative force that 'pulls' it back. But how can we explain the nature of this force in terms of the electrostatic/electromagnetic forces between charged atomic...

(a). Since K = W = Integral ( F dx ) and F = Fx = -6x K = -3 (x ^2) evaluate from 0 to 4 = 48 m/2 v^2 = 48 v = 6.9m/s correct? (b). since m/2 v^2 = -3x^2 and v = 5 x = sqrt ( -25/3 ) is not right because it would give me a complex number... Please...

When a 80.0kg mass is placed (not dropped) on topof a spring, the spring is depressed by 20 cm. The same spring is then used to launch a 2.0 kg object vertically. If the spring is compressed 5.0 m by pushing it down, and the object is then placed on top and the spring released, what will be...

I'm just having some trouble with this problem. Any help would really be appreciated. I'm not even sure where to start. A spring (not ideal) supplies a force given by F = zx^2, where x is measured from the equilibrium position and z is a constant. A mass m is attached to the spring and then...

I am having problems with this question: An m = 2.12 kg box rests on a plank that is inclined at an angle of q = 64.5° above the horizontal. The upper end of the box is attached to a spring with a force constant of 15.2 N/m. If the coefficient of static friction between the box and the...

so i have tried this problem fifty million times and i can't get the right answer. hopefully someone can help. when a 75 g mass is suspended from a vertical spring, the spring is stretched from a length of 4.0 cm to a length of 7.0 cm. If the mass is then pulled downward an additional 10 cm...

I am having trouble with this part of the problem. I set it up like this: -.5*m*v^2 = -.5*k*d^2 so v = sqrt((k*d^2)/m) = sqrt((220*.14^2)/.25) = 4.15 m/s. What am I doing wrong? A 250 g block is dropped onto a relaxed vertical spring that has a spring constant of k = 2.2 N/cm (Figure 7-42)...
