Answer 1

A light bar AB supports a 15-Kg block at its midpoint C, Rollers at A and B rest against frictionliess surfaces, and a horizontal cable AD is attached at A. Determine (a) the tension in cable AD, (b) the reactions at A and B

Answer 5

Since the surfaces are frictionless, the reaction at A is weight of the block. So, Ra = 15g N
The reaction at B is tension in the cable AD. So, Rb = T.

Answer 6

To find tension T in the cable, write the torque equation for torque of the bar about B.
The equation should be
\(Ra \times AD = W \times AD/2 + T \times BD \)
Solve this for T.
