A 3.10-mm-long, 430 kgkg steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 69.0 kgkg construction worker stands at the far end of the beam. What is the magnitude of the gravitational torque about the point where the beam is bolted into place?

Explanation:

Given that,

The length of the beam L = 3.10m

The mass of the steam beam = 430kg

The mass of worker = 69.0kg

The distance from  the fixed point to centre of gravity of beam =

and our length of beam is 3.10m

so the distance from  the fixed point to centre of gravity of beam is

Then the net torque is

is the weight of steel rod

is the weight of the worker

Torque can now be calculated

≅ 9169Nm
