Question

A 8-m-long, 510 kg steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 66 kg construction worker stands at the far end of the beam. What is the net torque on the beam

Answer 1

`T=25166.4Nm`

Step-by-step explanation:

From the question we are told that:

Mass of beam
`m_b=510kg`

Length
`l=8m`

Mass of Worker
`M_w=66kg`

Given the Weight acting on the Beam

Generally the equation for net torque on the beam is mathematically given by

`T=(l)/(2)m_bg+(lm_wg)`

`T=(8)/(2)*510*9.8+(8*66*9.8)`

`T=25166.4Nm`

`T=25.2kNm`
