Question

A 73.5 kg person sits on a 3.20 kg chair. Each leg of the chair makes contact with the floor in a circle that is 1.74 cm in diameter. Calculate the pressure exerted on the floor by each leg of the chair, assuming the weight is evenly distributed.
bobpursley
find the total weight, mg. Divide it by 4, for each leg force. Next, find the area of each contact point (PI(d/2)^2). change d to meters first.

Then, pressure= forceeachleg/areaeachleg
