Explanation / Answer

Given,

W = 190 N ;

theta = tan^-1(3/4) = 36.9 deg

a)considering the sum of torques

0 = -W x 2 - 300 x 4 + T sin(theta) x 4

T = 2 x 190 + 300 x 4/4 sin36.9 = 658 N

Hence, T = 658 N

b)Only cos component of T acts in honrizontal.

Fh = T cos(theta)

Fh = 658 x cos36.9 = 526.2 N

Hence, Fh = 526.2 N

c)In vertical direction:

Fv = 190 + 300 - 658 sin 36.9 = 95.2 N

Hence, Fv = 95.2 N
