One kind of stress is called pressure. pressure is calculated as force divided by area. force is a push or a pull. it is measured in units such as pounds or newtons. area is measured in units such as square inches or square meters. the equation for calculating pressure is p=f/a where p is pressure, f is force, and a is area. use the equation to calculate the average pressure on the membrane below. express your answer in units of pounds per square inch (psi).\

equation- f=60lb. a=24sq. in.
