Explanation of Solution

The device which is used to convert the electrical energy into mechanical energy is called motor. Rectifier is device which is used to convert the AC voltage into DC voltage.

In large DC controller motors, SCR (silicon controlled rectifier) is used to convert the AC voltage into DC voltage.

Thus, the electric component which is used to convert the AC voltage to DC voltage in large DC motor controllers is SCR.

A countershaft carrying two V-belt pullets is shown in the figure. Pulley A receives power from a motor through a belt with the belt tensions shown. The power is transmitted through the shaft and delivered to the belt on pulley B. Assume the belt tension on the loose side (T1) at B is 30% of the tension on the tight side (T2). (a) Determine the tension (i.e., T₂ and T₁) in the belt on pulley B, assuming the shaft is running at a constant speed. (b) Find the magnitudes of the bearing reaction forces, assuming the bearings act as simple supports. (c) Draw shear-force and bending moment diagrams for the shaft (in XZ and XY plane if needed). (d) Calculate the maximum moments at points A and B respectively and find the point of maximum bending moment (A or B). (e) Find maximum stresses (tensile, compressive, and shear stresses) at the identified point of maximum moment (hint: principal and max shear stresses) 8 dia. 9 400lbf 50lbf 45° 1.5 dia.

The cantilevered bar in the figure is made from a ductile material and is statically loaded with F,, = 200 lbf and Fx = F₂ = 0. Analyze the stress situation in rod AB by obtaining the following information. Note that the stress concentration factors are neglected in the following questions (Kt and Kts=1). (a) Determine the precise location of the critical stress element. (b) Sketch the critical stress element and determine magnitudes and direction for all stresses acting on it. (Transverse shear may only be neglected if you can justify this decision.) (c) For the critical stress element, determine the principal stresses and maximum shear stress. 6 in 1-in dia.
