Explanation / Answer

here,

wA = 44 N , wB = 50 N

phi = 34 degree

a)

for A

equating the forces vertically

T1 * cos(phi) = wA

T1 * cos(34) = 44

T1 = 53.1 N

b)

equating the forces horiontally

T2 = T1 * sin(phi)

T2 = 53.1 * sin(34) = 29.7 N

c)

for B

equating the forces horiontally

T3 * sin(phi) = T2

T3 * sin(phi) = 29.7 ...(1)

and equating the forces vertically

T3 * cos(theta) = wB

T3 * cos(theta) = 50 ....(2)

from (1) and (2)

theta = 30.7 degree

T3 = 58.2 N

d)

theta = 30.7 degree
