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.
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).
