Consider the following. (a) The nail puller shown in the figure above is designed such that you exert a force 34.0 cm from the pivot and the nail is 1.95 cm from the pivot on the other side. Determine the mechanical advantage of the nail puller. (b) Determine the minimum force must you exert in order to apply a force of 1400 N to the nail. N (c) If the nail puller has a mass of 2.10 kg, determine the force the nail puller exerts on the supporting surface. magnitude N direction For part c there are 4 forces acting on the nail-puller: The force from the hand, the force of gravity/weight, the force of the nail pushing back on the nail-puller, and the normal force from the ground.
