To identify the conceptual properties of simple trusses. A truss is a structure composed of slender members that are connected at their ends. Planar trusses lie in a single plane and are often used to support roofs and bridges. In designing a truss's members and connections, three assumptions are made: All loadings are applied at the joints. The members are connected by smooth pins. All members in a truss are straight. Each member acts as a two-force member and the forces at the ends of the member must be directed along the member's axis. Because trusses consist of two-force members, each member is either in tension (being pulled apart) or in compression (being pushed together).

An electric motor is used to drive a power press which makes steel turning moment diagrams 323 pressings from a metal sheet. the motor runs at a mean speed of 50 rev/s. the torque required is 10.0nm for 0.2s, followed by 1.0nm for0.3 s with this sequence then being repeated. what is the minimum power required of the motor and the moment of incrtia required for the t1ywhcel if the speed fluctuations are to be restricted to 1.5%?
