Problem 1: For the following truss, each member has the same EA. All members are pin connected at their joints.
(i) Under the loads at C and D, determine the displacement of joint D along the CD direction (20')
(ii) Without consideration of the loads at C and D, if the member CB is fabricated 1 inch too short, determine the horizontal displacement of joint D (20').
Problem 2: For the following beam with EL being constant. Assume the support at A is a pin and C is roller.
(i) Determine the maximum deflection of the beam and its location (20')
(ii) Now another roller is added at B under the beam to reduce the deflection of the beam. Calculate the force at the roller B and the maximum deflection of the beam again (40')
Determine the position x and the tension in the cord that is required for equilibrium. The cord passes through the smooth ring at B and has an unstretched length of 6ft and stiffness of k = 50lb/ft.
An intercom system has a 13 kHz annoying whistle with amplitude of 20% of a typical voice signal. Assume that a typical voice signal has a frequency of 3 kHz and the intercom's output for a typical voice level has amplitude of 10V.
