Piston rod 5 mm 50 mm 225 mm P = 40 N Problem 1.2-2 Calculate the compressive stress s c in the circular piston rod (see figure) when a force P 5 40 N is applied to the brake pedal. Assume that the line of action of the force P is parallel to the piston rod, which has diameter 5 mm. Also, the other dimensions shown in the figure (50 mm and 225 mm) are measured perpen- dicular to the line of action of the force P . Solution 1.2-2 Free-body diagram of brake pedal Problem 1.2-3 A steel rod 110 ft long hangs inside a tall tower and holds a 200-pound weight at its lower end (see figure). If the diameter of the circular rod is 1 / 4 inch, calcu- late the maximum normal stress
