Question

In a jib crane, the jib and tie rod are 6 m and 5 m long respectively. The height of the crane post is 3 m. When a weight (W) 317 N is suspended from the crane and the tie rod remains horizontal.

Determine the tension in Tie rod (only magnitude, in N)?

Answer 1

$\tan\theta = \dfrac{6}{5}$

$\theta = 50.19°$

$\textsf{Tension}= \dfrac{317\ N}{\sin 50.19°}= 412.67\ N$
