Chapter 12: Q. 59 (page 333)

In Figure P12.59, an 80 kg construction worker sits down 2.0 m from the end of a 1450 kg
steel beam to eat his lunch. What is the tension in the cable?

Short Answer

Expert verified

The tension in the cable is 1.53 x 10⁴ N

Step by step solution

Given Information

Mass of worker = 80 kg

worker sits 2.0 m from the end

Mass of steel beam = 1450 kg

Explanation

First draw the diagram as below to understand and solve the problem

And then equate the clockwise and anti-clock wise torque about the origin

We, get

$W_{b} \times 3 m + W_{w} \times 4 m = T s i n 30 ° \times 6 m$

Substitute the given value and solve for T

use weight as mg .. so multiply mass with g.

$T = \frac{(1450 kg \times 9.8 m / s^{2} \times 3 m) + (80 kg \times 9.8 m / s^{2} \times 4 m)}{6 m \times \sin 30 °} T = 15, 255.3333 N T = 1.525 \times 10^{4} N$
