Question

The problem reads: The 25-lb double pulley shown is at restand in equilibrium when a constant 3.5 lb ft couple M isapplied. Neglecting the effect of friction and knowing thatthe radius of gyration of the double pulley is 6 in., determine a)the angular acceleration of the double puuly )b the tension inreach rope. I am have a problem generating the free-body diagram and thedifferent radii of each pund away from the center is throwing meoff. the distance to A (10lbs) is 4 in and the distance to B(5 lbs) is 8 in. Please help me out, it would be greatlyappreciated. Thanks The problem reads: The 25-lb double pulley shown is at restand in equilibrium when a constant 3.5 lb ft couple M isapplied.

Explanation / Answer

why is it that when summing the moment of the drum, weight A, and weight B in order to get the total sum of moments (in which we found the angular acceleration) that we add the moments of A and B even if they go in opposite directions?
