A 100 kg block rests on an incline. The coefficient of static friction between the block and the ramp is 0.2. The mass of the cable is negligible, and the pulley at point C is frictionless. What is the smallest block B mass that will start the 100 kg block moving up the incline?

The weight of a 500 kg homogenous crate is supported by three wall-mounted cables, as shown. If the force in cable AD is 5950 N, most nearly, what is the sum of the x-components in cables BD and CD?

What is most nearly the magnitude of the x-component of the 300 N force at point D on the member shown?
