In the figure, the diver is simply standing at the end of the board, before beginning her diving action. The distance from support post B to the position of the diver's feet is L~=~ 2.1 m, and the distance from support post B to support post A is d~=~ 1.110 m. The weight of the diving board is 230 N and the mass of the diving board is uniformly distributed.
Find the magnitude of the force exerted on the board by the supporting structure at point A.
t = torque
t = F*r
The Attempt at a Solution
For the first part of the question i had to find the torque on the front support B.
t = F*r
t = 58(9.8)(2.1) = 1193.6 Nm
From here i thought to get the force on point A i could
find the torque on point A and subtract the torque at point B
ta = 58(9.8)(2.1+1.11) = 1824.56
ta = 1824.56 - 1193.6 = 630.96
then to solve for the force on point a
Fa = ta/(2.1+1.11)
Fa = 630.96/(2.1+1.11) = 196.56 N
Does this look right? I feel it is wrong.
Thank you for any help :)
