29 Newtons. Simple multiplication.
Since you do not tell us the context of this scenario, we have no way of knowing.
The idea is to divide the output force (the amount of weight it can lift in this case) by the input force.
85 newtons, up . =================== Nope. The force of gravity is 35 newtons, directed down. The force of your mighty out-stretched arm is 50 newtons, directed up. The net force on the book is 15 newtons directed up, so that's the direction in which the book accelerates. (At 15/35 = 3/7 of a 'G' .) Exactly the same analysis as you'd apply to a rocket launch.

Force the lever will apply to the load being lifted.
output force
A force and an energy are two quite different things. Energy is spent if you apply a force for a certain distance, so energy has units of force x distance (in the SI, newtons x meters).
Any force greater than 980 newtons.
If the machine were ideal ( 100% effiency) the output force would be 300 N In practice you might get 250 - 270.
1/4 the output force.
