Note: Read the question carefully and give me right solutions according to the question.
The assembly is used to support a distributed loading of w = 6.6 kN/m. The solid steel rod BC has a diameter of 13 mm and the steel pins at A, B and C have a diameter of 10 mm. The yield stress of the steel in tension is 250 MPa and in shear is 125 MPa. C 1.2 m 0.9 m 0.3 m Determine the factor of safety for the pin at B with respect to yielding?

A clamp coupling is to transmit a power of 13 kW to a shaft rotating at a speed of 511 rpm. Calculate the diameter of the shaft if the allowable shear stress on the shaft is 45 MPa. The number of bolts connecting the two halves is six. The permissible tensile stress for the bolts is 76 MPa. The coefficient of friction between the coupling and the shaft surface may be taken as 0.3. Also, find the diameter of the bolt. Torque in Nm Diameter of shaft in mm Diameter of bolt in mm
A single block brake is shown in the figure. The diameter of the drum is 250 mm and the angle of contact is 103.7°. If the operating force of 661N is applied at the end of a lever and the coefficient of friction between the drum and the lining is 0.35, determine: a. The tangential braking force, Ft, in Newtons b. The braking the torque transmitted by the block brake in N-m.
