Question

A uniform strut of mass m makes an angle (theta) with the horizontal. It is supported by a frictionless pivot located at one-third its length from its lower left end and a horizontal rope at its upper right end. A cable and package of total weight hang from its upper right end. Find the vertical component of the pivot's force on the strut. Find the horizontal component of the pivot's force on the strut. Find the tension T in the rope. If the maximum safe tension in the rope is 750 N and the mass of the strut is 28.0 kg, find the maximum safe weight of the cable and package when the strut makes an angle of 50.0 degrees with the horizontal. For what angle (theta) can no weight be safely suspended from the right end of the strut?

Explanation / Answer

T=(w+(mg/4))cot(angle)
