A participant in a "strongman" competition uses an old-fashioned device to move a large load with only muscle power. A 85-kg bucket of rocks is suspended from a sturdy, lightweight beam 0.78 m from a pivot. The man lifts the beam at its end, 3.0 m from the pivot, and holds it steady. Use g = 10 m/s2. How much force must the man apply, in Newtons? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

Can you draw a free-body diagram of this problem? Three children are trying to balance on a seesaw, which includes a fulcrum rock acting as a pivot at the center, and a very light board 3.2 m long as shown in the figure. Two playmates are already on either end. Boy A has a mass of 45 kg, and boy B a mass of 35 kg. Where should girl C, whose mass is 25 kg, place herself so as to balance the seesaw?
A beam resting on two pivots has a length of L = 6.00 m and mass M = 92.0 kg.The pivot under the left end exerts a normal force n1on the beam, and the second pivot placed a distance ℓ = 4.00 m from the left end exerts a normal force n2.
