## bii17 2 years ago The oil drum weighs 620 lb when full and has a mass center at G. Calculate the vertical force P required to maintain equilibrium of the drum and dolly in the position shown. The weight of the dolly may be neglected compared with that of the drum. Picture: http://tinypic.com/r/2po38fp/5

help pls

6. ankit042

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

7. bii17

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

8. bii17

it will be like this?

9. ankit042

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

10. bii17

yes.. and then what will happen next?

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

13. bii17

how? what will be the solution?

14. ankit042

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
