Rigid bar ABC is supported by member (1) at B and by a pin connection at C. Member (1) has a cross sectional area of 1.00 in.² and a yield strength of 33 ksi. The pins at B, C, and D each have a diameter of 0.3 in. and an ultimate shear strength of 78 ksi. Each pin connection is a double-shear connection. Specifications call for a minimum factor of safety in member (1) of 1.3 with respect to its yield strength.

It is connected to a support at A and to member BCD at C by-in.-diameter pins, while member BCD is connected to its support at B by a -in.-diameter pin. All of the pins are made of a steel with a 25-ksi ultimate shearing stress and are in single shear. Knowing that a factor of safety of 3.25 is desired, determine the largest load P that can be applied at D. Note that link AC is not reinforced around the pin holes.

A four story "intermediate reinforced concrete moment frames" supports seismic weights of 1400 kip on each floor and 500 kip on the roof. The natural (fundamental) period of this frame as T-0.6 sec. Based on ASCE 7-16 procedures, the base shear this frame must resist in an earthquake is V-846 kip 14 ft 14 ft 14 ft 14 ft A A 7777 7777 777 w=500 kip w=1400 kip w=1400 kip w=1400 kip 7777 1. Based on the natural period, linearly interpolate the value of k that should be used for the equivalent lateral force method. 2. Using your interpolated value of k and the base shear, compute the vertical distribution of lateral loads. 3. Draw an elevation of the frame showing the lateral loads applied to each floor and the roof. 4. Assuming k-2, compute the vertical distribution of lateral loads. 5. Draw an elevation of the frame showing the lateral loads applied to each floor and the roof when k=2.
Design a clamp coupling to transmit 25 kW at 120 r.p.m. The allowable shear stress for the shaft and key is 50 MPa and the number of bolts connecting the two halves are six. The permissible tensile stress for the bolts is 75 MPa. The coefficient of friction between the muff and the shaft surface may be taken as 0.3.
