The drawing shows a person (weight W = 592 N, L1 = 0.841 m, L2 = 0.410 m) doing pushups. Find the normal force exerted by the floor on each hand and each foot, assuming that the person holds this position. force on each hand N
force on each foot N

It is difficult to decipher the figure. Sum moments about any point, and the sum of vertical forces equals zero. Those two equations should give you a system of equations to solve.
