Question

Determine the value of the force exerted by the fulcrum (F) and weight to keep the bar in equilibrium. Weight is applied on the center of gravity.

PLEASE DO HELP. REALLY NEED IT.

Answer 1

here's the picture/diagram. :)

Answer 2

@hartnn @nubeer @Callisto hey guys, can you do this problem? really need ur help right now. :(

Answer 3

in your picture are the red and green forces acting down(like gravity) and the purple is pulling up?..slash what is the 30N to the left

Answer 4

Are you given the purple value?

Answer 5

yup. they're all the vector forces. i mean they're all forces acting on the object.

Answer 6

no. we're not. sorry. :(

Answer 7

kk, so you are going to want to balance your forces in all directions

Answer 8

so find the force of the purple one, you know that its x component must equal the 30N since it is the only other force acting in that direction

Answer 9

yup. :)

Answer 10

you want to find x

Answer 11

that will be the force in the y direciton due to the purple vector

Answer 12

so now you have 20 and 10 forces acting down. and x and the fulcrum acting up

Answer 13

just balance the forces...i was about to do torque here..but i dont think you have to

Answer 14

yup. ;)
