help pls

ankit042 · Answer

can you start with drawing a Free body diagram of all the forces

anonymous · Answer

hmm. there will be a vertical force on the part of the wheel. @ankit042

anonymous · Answer

it will be like this?

ankit042 · Answer

Yes and one more force will be from the weight of oil drum. This will be present at center of Gravity

anonymous · Answer

yes.. and then what will happen next?

ankit042 · Answer

Now as the system is under equilibrium you have to balance the torque and forces

anonymous · Answer

how? what will be the solution?

ankit042 · Answer

Sorry I have to leave now....but you have two variables Fv and P and you can get your answer by balancing torque and forces. You might want to post this question in physics section

i already posted it there but no one answer it
