Question

You're carrying a 3.0-m-long, 24 kg pole to a construction site when you decide to stop for a rest. You place one end of the pole on a fence post and hold the other end of the pole 35 cm from its tip. How much force must you exert to keep the pole motionless in a horizontal position?

Answer 1

`F=133N`

Step-by-step explanation:

From the question we are told that:

Length
`l=3.0m`

Mass
`m=24kg`

Distance from Tip
`d=35cm`

Generally, the equation for Torque Balance is mathematically given by

`mg(l/2)=F(l-d)`

`2*9.81(3/2)=F(3-35*10^-2)`

Therefore

`F=133N`
