To determine Determine the distance b . Explanation Show the free body diagram of the slender bar as in Figure (1). Write summation of forces in t direction. ∑ F t = m a t F = m a A (I) Here, mass of the slender rod is m , applied force is F and acceleration of rod A is a A . Consider summation of moments about centroid G by considering moments in anti-clockwise direction as positive. ∑ M G = I G α + m a d F x = 1 12 m l 2 α + m ( x a ) x (II) Here, moment of inertia about centroid is I G , angular acceleration of the bar is α , the distance of point F from centroid is x and length of the bar is l . Express the distance b . b = ( 0.8 m ) − x (III) Conclusion: Substitute 20 m / s 2 for a A in Equation (I)

Spur gears Note : Exam is open notes &tables / Answer all questions. Q.1. The press shown for Figure.1 has a rated load of 22 kN. The twin screws have double start Acme threads, a diameter of 50 mm, and a pitch of 6 mm. Coefficients of friction are 0.05 for the threads and 0.08 for the collar bearings. Collar diameters are 90 mm. The gears have an efficiency of 95 percent and a speed ratio of 60:1. A slip clutch, on the motor shaft, prevents overloading. The full-load motor speed is 1720 rev/min. (a) When the motor is turned on, how fast will the press head move? (Vm= , Vser. = ) (5M) (b) What should be the horsepower rating of the motor?
