Homework Statement
A hand truck is used to move two barrels, each weighing 80 lb.
Neglecting the weight of the hand truck, determine (a) the vertical force P
which should be applied to the handle to maintain equilibrium when
α = 35°, (b) the corresponding reaction at each of the two wheels.

Go to prob. 4.5!
Homework Equations
Sum of all forces = 0
Sum of all moments = 0
The Attempt at a Solution
I honestly just don't understand this period. As far as I got was to make a big triangle where it's 64sin35 to find the side on the ground which is 52.42 which would give us the M= rxF for P. 52.42xP at Mb. Ohhhh, would I have to do that for the forces at g2 and g1 (to find the sides on the 'ground' and cross it with the weights to find P in the equation of the sum of the moments? If so, what about for part b?
Thanks a lot in advance!
