- A shaft turning 200 RPM is to drive another shaft at 250 RPM connected in open belt. Find the diameters of the two pulleys, using integral number of inches for each diameter, to give as nearly as possible a belt speed of 3500 FPM.Below question is from machine design. Please solve asap. You have to select bearings which are used to support a shaft, bearings are mounted at each end of shaft and 1.20 metre apart. A 600 mm diameter pulley is mounted at a distance of 300 mm to the right of left hand bearing and this drives a pulley directly below it with the help of belt having maximum tension of 2.25 kN. Another pulley 400 mm diameter is placed 200 mm to the left of right hand bearing and is driven with the help of electric motor and belt, which is placed horizontally to the right. The angle of contact for both pulleys is 180º and .Allowing working stress of shaft depends on the material you have selected for the shaft. Select the type of bearing mounted on both ends of shaft (either ball or roller bearing type and also elaborate the scenario for the selection of bearing).The Reliability Factor for Bearing may vary from 92% till 96%A shaft turning 150 RPM is to drive another shaft at 200 RPM. Find the diameters of the two pulleys, using integral number of inches for each diameter, to give as nearly as possible a belt speed of 2500 FPM. Please provide illustration.
- 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.Please solve ellaborately and include the untis in every step, show diagram and write your solutions clearly and readable if your solution is in written form.

Determine (a) diameter of the driven pulley for open belt drive,(b) speed of the driven pulley, and (c) belt length for an open belt connection. (a) Diameter of Driven Pulley Answer and unit for part 1 (b) Speed of the Driven Pulley Answer and unit for part 2 (c) Belt LengthPlease solve ellaborately 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, each carrying a four-stepped pulley, are to be connected by a crossed belt. The driving shaft is to turn 150 rpm while the driven shafts is to turn 50, 150, 250 and 600 rpm. The smallest step of the driver is 10 in. in diameter. Find the diameters of all steps. Please Show a clear and detailed solution (with illustration). Thank you!9A pump is driven by an electric motor through a open type flat belt drive.Motor pulley diameter (DS) = 300 mm, Pump pulley diameter (DL) = 600 mm. The Center distance between the pulleys=1000 mm. Find the length of the belt in inches
- TRUE OR FALSE. ANSWER ALL QUESTIONS OTHERWISE DONT ATTEMPT IT STRICTLY. I WILL REPORT YOU IF U ATTEMPT WITHOUT ANSWERING ALL QUESTIONS.Find the standard distance between sprocket having 4 in and 16 in diameters.A lathe having a 5-step pulley is driven by a belt, assumed to be crossed, from a pulley of the same size on the countershaft. The countershaft is to have a constant speed, and the lathe is to have speeds of 60 rpm and 135 rpm when the belt is on the steps either side of the center step. If the minimum speed is 40 rpm and the smallest diameter is 4 in., find theproper speed of the countershaft, maximum speed of the lathe, and the diameter of all steps on the pulleys.
