1. The problem statement, all variables and given/known data A 72 kg person sits on a 4.0 kg chair. Each leg of the chair makes contact with the floor in a circle that is 1.1 cm in diameter. Find the pressure exerted on the floor by each leg of the chair, assuming the weight is equally distributed. 2. Relevant equations P=F/A A=∏r^2 3. The attempt at a solution To find the force, I added the mass of the person and the mass of the chair and got m=76kg. Then i multiplied that by g=9.81 and got F=745.56. To find the area, I converted 1.1 cm into meters, .011, and found the area A=9.5*10^-5 then i divided F/A and got P=7845260 but this is incorrect.
