When a wood shelf of mass 6.1 kg is fastened inside a slot in a vertical support, the support exerts a torque on the shelf.

Question

The board is 32cm wide by 3cm tall. the slot is 2 cm wide (3cm tall)on the lefthand side.

So there are three vertical forces.

A) Calculate the upward force. (I got 510N)

B)Calculate the downward force (I got 450N)

C) w = ? (how do i find this???)

D)Calculate the torque exerted by the support (about the left end of the shelf).

You can do it on a scanner or jpg, and upload it. Post the url link here.

Answer 3

it won't let me post it. apparently it seems to be 34cm long, 2cm of which is inserted in in the slot. so the block is 34cmx3cm inserted in a 2cm long slot on the left.
