Please solve ellaborately using the equation provided in the figure and include the untis in every step, show diagram and write your solutions clearly and readable if your solution is in written form. Your work will be appreaciated much. Thank You.   Two shafts, 1.67 ft apart, are connected by an open belt. The input shaft has a speed of 350 rpm and the output shaft should be capable of running at speeds of 950 rpm, 650 rpm, 450 rpm, 250 rpm, and 150 rpm. If the diameter of the smallest pulley on the driven shaft is 2 inches, calculate the length of the belt and the diameters of each pulleys attached at the shafts.

Use the drawing below to answer the following two questions. a. Determine the equivalent spring stiffness of the following system. Simplify the expression (ie – single common denominator. Your answer should be an expression of just K’s – no numbers). b. If the weight on top is 20 lb and the K1 = K4 = 50 lb/in, K2 = 33 lb/in and K3 = K5 = 25 lb/in, what is the natural frequency of the system?

The machine is designed to be powered by a 100 HP electric motor at a speed of 1500 rpm, with standard D-120 V-belts. The pitch diameter of the smaller sheave is 101.6 mm and the bigger sheave is 406.4 mm. Service factor is 1.25. Use length of D-120 V-belt equal to 123.3 inches. Determine the center distance between sheaves in mm; the arc of contact in deg; and the design in HP.

What weight (kg) can be lifted by a double threaded screw that has an efficiency of 85% if it is opetated by a 52 lb force at the end of a 25 inches lever ?The pitch of the screw is 0.55 inches

3. Determine the principal dimensions of a cone faced with leather to transmit 30 kW at 750 rpm from an electric motor to an air compressor. Sketch a sectional front view of the clutch and provide the main dimensions on the sketch. Assume: semi-angle of the cone = 12 1/2°; f = 0.2; mean diameter of cone = 6 to 10d where d is the diameter of shaft; allowable normal pressure for leather and cast iron = 0.075 to 0.1 N/mm²; load factor = 1.75 and mean diameter to face width ratio = 6.

The circuit has been designed to crush a car body into bale using a 150 mm diameter hydraulic cylinder. The hydraulic is to extend 2.50 m during a period of 10s. the time between crushing strokes is 8 min. the following accumulator gas absolute pressures are given: P1 = Gas precharge pressure 90bar(abs), P2 = Gas charge pressure when pump is turned on 200 bar(abs) = pressure relief value setting,P3 = Minimum pressure required to actuate load 125 bar (abs).Calculate: (i) the required size of the accumulator (ii) What are the pump hydraulic kW p

Thank You!   Two shafts 30 in. apart, each carrying a four-step pulley, are to be connected by a crossbelt. The driving shaft is to turn 180 rpm while the driven shaft is to turn 50, 150, 250,and 600 rpm. The smallest step of the driver is 10 in. in diameter. Find (a) the diametersof all the steps, (b) angle of contact for each pair of pulleys, and (c) belt length.
