Question #3962

Calculate the force needed to hold a 2000 kg car on a ramp that makes an angle of 30 degrees with the horizontal, if the force is to be applied parallel to the ramp.

Expert's answer

Refer to the image below:

The force required to hold 2000 kg car is equal to the projection of the weight on the ramp:

F = mg sin 30 = 2000*10*1/2 = 10 000 N.

The force required to hold 2000 kg car is equal to the projection of the weight on the ramp:

F = mg sin 30 = 2000*10*1/2 = 10 000 N.
