Question
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 4m. Radius of the wheel is 1m and its mass is
- 100 N
- 66 N
- 167 N
- 133.3 N
The correct answer is: 133.3 N
applying principle of moments
F (0.6)=100(0.8)
ÞF=133.3N
