Thanks for your questions buddy  ;)

Vin:
I need help. :/ This seems to be an easy question but I don't get it at all.

Pg. 111, Q.3 From the book International A/AS Level Physics by Chris Mee, Mike Crundell and others.

A uniform plank of weight 120 N rests on two stools as shown in Fig. 4.39. A weight of 80 N is placed on the plank, midway between the stools. Calculate :
(a) the force acting on the stool at A,
(b) the force acting on the stool at B.

Thanks a lot!

Vin:
Oh, By the way the answers are (a) 80 N and (b) 120 N. Just in case. ;)

Are you sure about the answers dude?

Because am getting (a) 88N and (b) 112N

I think there must be some kind of misprint in the book ;)
