A uniform drawbridge must be held at a 37 ∘ angle above the horizontal to allow ships to pass underneath. the drawbridge weighs 45,000 n and is 14.0 m long. a cable is connected 3.5 m from the hinge where the bridge pivots (measured along the bridge) and pulls horizontally on the bridge to hold it in place. part a what is the tension in the cable?

Tension may be defined as the pulling power transferred axially through a cable, string, chain, or alike one-dimensional unceasing object, or by separately end of a rod.

To compute for tension:

Sum the moments about the pivot:

ΣM = 0 = T * 3.5m * sin37 º - 45000N * 7.0m * cos37º

tension T = 119 434 N
