The base of compression-type spring balance is rigidly bolted to the floor inside the car. The spring inside the blance has a spring constant $k=10^4 Nm^{-1}$. box of mass $m=100kg$ is rigidly bolted to the weighing pan of the balance. (The mass of the box is much greater than the mass of the...

Thanks :D I got my answer F=283N Is that right?

I mean,the normal force act on the cylinder by the floor.

How about the normal force acting on the cylinder? Why it is not in consideration?

Hi, I think that this question need the idea of torque. But i m get stuck in choosing which point and what forces should be included. Here it is : A cylinder with mass m=50kg located as shown in the figure. Given that h = 0.5r A force F is applied tangentially to the axle to lift the...

The first part is OK for me, but the second part seems very complicated.

A small crate of weight 5.0N is released from rest at a height 2.0m up a smoyj inclined plane. The crate slides down the plane and across a smooth 1.50m floor to a rough plane where a spring is located. The bottom of the spring is located at a height of 0.5m. The spring constant is 20N/m ...
