Asimply supported beam, 4" wide, 6" deep, and 16 ft. long carries a uniformly distributed load of 300 lb/ft (a) compute the shearing stress developed at horizontal layers that are 1" apart from top to bottom of a section that is 2 ft. from the left end. (b) compute the maximum shearing stress developed in the beam.

Plss anybody know how to do this? ? i need the answers from a through d

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
