Determine the range of the force P that will keep the crate A in equilibrium. Crate A has a mass of 968kg, the angle alpha is 65 deg, the angle Theta is 25 deg, pulley C is frictionless, and the two drums B and D are fixed. The coefficient of friction between the crate and the slopped surface is mu = 0.25, between the rope and the fixed drum B mu = 0.20, and between the rope and the fixed...

Tensions on ropes in a pulley
The pulley system shown in the figure is used to lift a 52-kg crate. Note that one chain connects the upper pulley to the ceiling and a second chain connects the lower pulley to the crate. Assume the masses of the chains, pulleys, and ropes are negligible. Determine the force \(\vec{F}\)
required to lift the crate with constant speed, determine the tension in the upper chain, and determine the tension in the lower chain.

Near the surface of the Earth, a student is using a simple pulley to lift a crate of mass M = 30 kg from rest to a height H by pulling on the rope with a constant force F as shown in the figure. If the breaking strength of the rope is 400 N, what is the minimum time (in s) required for the student to haul the crate to a height H = 20 m? (Assume that the pulley...

Another method that could be used to solve for the desired
quantities in the problem, other than using a force triangle, would
be to use equilibrium with the components of all forces acting at
point A. Rank the following steps in the order they would need to
be implemented to solve the given problem using force
components.
