Question: ( 4 ) blocks: W A = 3 8 N W B = T B D coefficient of static friction: s = 0 . 4

(4)

blocks:

W_{A} = 38 N

W_{B} = T_{B D}

coefficient of static friction:

_{s} = 0.40 (

for both.

A and

B)

Two blocks are located on surfaces, as shown, and are connected by a cord that passes over a frictionless pulley, also as shown. Find the maximum weight

W_{B}

that is consistent with equilibrium.

(

Assume that the cord remains taut.
