Calculate the force `F` that is applied horizontally at the axle of the wheel which is necessary to raise the wheel over the obstacle of height `0.4 m`. Radius of wheel is `1m` and `mass = 10 kg` . `F` is

A

`100N`

B

`66N`

C

`167N`

D

`133.3N`

Text Solution

Verified by Experts

The correct Answer is:
D
Taking moment of forces about point `P` , we get

`Fxx0.6=100xx0.8`
or `F=(10xx0.8)/0.6=B=800/6N=400/3N=133.3N`
