A force of F pounds is required to pull an object weighing W pounds up a ramp inclined at θ degrees from the horizontal. Find F if W=100 pounds and θ=11degrees

A force of 35 N pushes three boxes along a horizontal surface. Find the contact force between 2 kg box and 1 kg box. (ans:5N)

A horizontal force of 430 N is applied to a stationary wooden box in one direction, and a 700 N horizontal force is applied in the opposite direction. What additional force is needed for the box to remain stationary?

inclined at an angle of 26.6º. Since the box is on wheels, assume that friction is negligable. A mover is pushing a 122 kg box up a ramp. The ramp is inclined at an 0 (A) Calculate the force the mover exerts to push the box up the ramp at a constant rate of 1.4 m/s. Assume he pushes parallel to the ramp. (B) Calculate the force the mover exerts to push the box up the ramp at a constant rate of 1.4 m/s². Assume he pushes parallel to the ramp. (C) Calculate the normal force the ramp exerts on the box. 1069.05 N 4.

To be compliant with regulations the inclination angle of awheelchair ramp must not exceed 4.76°. If the wheelchair rampmust have a vertical height of 1.22 m, what is its minimum horizontal length?
