Answer 1

Explanation:

a)check attachment

b) The wheel came to rest due to the 2 forces.

torque is making it

torque at A=F1×2.5

torque at o` =F2×2

we can see that at point o` perpendicular distance is less than that of perpendicular distance at point A.

This implies that F2 is greater because the torque at both points some how same.With less perpendicular distance torque at o` can't sustain so the force may be large.

torque at A=torque at o`

F1×2.5=F2×2

F1/F2=2.5/2

F1/F2=5/4
