A rope ABCD is looped over two pipes as shown. Knowing that the coefficient of static friction is 0.25, determine (a) the smallest value of mass 'm' for which equilibrium is possible, (b) the corresponding tension in portion BC of the rope. в 27° A D 50 kg m E

A 3-m boom is acted upon by the 4-kN force shown. Determine the tension in each cable and the reaction at the ball-and-socket joint at A.

Knowing the tension in cable AC is 795 N, determine the components of the force exerted by the cable on the support at A. in this problem. The wooden board will not be in your FBD.)
