The tall man on stilts is stationary as he pokes fun at the shorter stilt-walkers. His body mass including the stilts is 70 kg and located at the CM labelled. The ground pushes upward on his right stilt (at P2) with a force of 309.5 N. The force of the ground on both of the stilts just happens to be purely vertical (no x components). a) Find the force of the ground on his left stilt (located at P3). b) Would the force of the ground on his left stilt (at P3) change if he was holding a gallon of milk (mass of 3.62 kg) in the hand he is pointing with? If F3 changed, what value will it increase or decrease to? As always when talking about forces you must us mechanical reasoning to support your answer. c) We can combine the two forces of the ground on this stilts into a single force and place that force at a new virtual point called the center of pressure. While he is holding the milk and still remaining stationary, would that center of pressure be located on a vertical line through the labelled CM? Include full mechanical reasoning. 0.420 0.092 V_ CM y 1.239 X PZ P3 0.148 10 1 0.122
