Question

A 1310 N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A W = 1970 N crate hangs from the far end of the beam.
a) Calculate the magnitude of the horizontal component of the force that the wall exerts on the left end of the beam if the angle between the cable and horizontal is θ = 47°.

A mass m₁ = 18.5 kg is connected by a light string that passes over a pulley of mass M = 14.5 kg to a mass m₂ = 9.00 kg sliding on an inclined frictionless surface that makes an angle of 25° with the horizontal (see figure). There is no slippage between the string and the pulley. What is the magnitude of the acceleration of the system of masses? (The moment of inertia of the pulley is ½Mr².)

i don't know about the first part but I have done 2nd one hope it will help you
