Question

Find the tension T2 of the box hanging from the rope if 1 = 25°, 2 = 65°, T1 = 60.58 newtons, and W = 143.4 newtons.


A.

95.6 newtons

B.

130 newtons

C.

143.4 newtons

D.

158.2 newtons

Answer 1

Answer:

130N

Explanation:

Find the diagram in the attachment.

Using sine rule to get T2 as shown in the last diagram

T1/sin65° = T2/sin25°

Since T1 = 60.58N

Then:

60.58/sin25° = T2/sin65°

Cross multiplying

T2 × sin25° = 60.58sin65°

T2 = 60.58sin65°/sin25°

T2 = 54.90/00.423

T2 = 129.78N

T2 is approximately 130N
