A 20 HP series-wound electric motor drives an extruder at 800 rpm for more than 20 hours per day. Sheave centers for a V-belt drive must be between 48 and 50 inches apart, and the belt speed needs to be limited to 5,000 fpm. Assuming the speed of the motor is 1,750 rpm, find: a. Standard belt size and length required (inches) b. Standard sheave diameters (inches) c. How many belts are required for this transmission? d. Using an 11 x 17 inch paper size format, draw the entire transmission in AutoCAD or SolidWorks, showing all relevant dimensions.

Please show step by step manual solution and diagram for Machine Elements 2 problem below.  .A pulley 600 mm. in diameter transmits 40 kW at 500 rpm. The arc of contact between the belt and pulley is 144°. Determine (a) diameter of the driven pulley for open belt drive, (b) diameter of the driven pulley for cross belt drive, (c) speed of the driven pulley, (d) belt length for open belt connection, and (e) belt length for cross belt connection.

A series of three links is given with lengths of 2.4 ", 7.2" and 3.4 ", select the length of a fourth link, that when assembling the mechanism one of the links can be driven by a motor that rotates continuously. Mechanism is according to Grashoff, show all your operations to justify your results

Please veryyy urgent with counting the numbers on graph and explain how to count j2 pls

Problem 4: Inputs: a = 4.5" (the "symbol indicates inches) b= 1/4" (rod diameter) ● F₁ = 13 lb ● Have you ever wondered how bolts get their threads? Well, we start with a smooth rod and then cut the threads into it. The thing that cuts the threads is called a "die." Although machines can be used for this process, it is often done by hand as well, and that's what we're looking at on the right. F₁ Handles a Die The "die" is in there a F₁ bk F₂ Threads Rod So suppose you want to cut threads on this rod. You would get the correct size die (they come in lots of different sizes), and place it inside the handle. Then you would twist the handles around the rod, thereby cutting the threads with each revolution. For this problem, suppose you apply a force of F₁ to the handles. What is the force F₂ exerted on the rod? Use couples for your solution. F₁

A V-belt drive is required for a 20 Kw, 1440 rpm electric motor which drives a compressor running at 480 rpm for a service of 15 hrs per day. For space consideration, the center distance should be approximately 1.2 m. Determine, i) belt specification ii) number of belts iii) correct center distance iv) pulley diameters.

The essential features of a transmission dynamometer are shown in figure below (all dimension in mm). A is the driving pulley which runs at 600 RPM. B and C are jockey pulleys mounted on a horizontal beam pivoted at D, about which point the compete beam is balanced when at rest. E is the driven pulley and all portions of the belt between the pulleys are vertical. A, B and C are each 300 mm diameter and the thickness and weight of the belt are neglected. The length DF is 750 mm. Find: 1. The value of the weight W to maintain the beam in a horizontal position when 4.5 kW is being transmitted, and 2. The value of W, when the belt just begins to slip on pulley A. the coefficient of friction being 0.2 and maximum tension in the belt 1.5 kN. Driven 15 soojade Driving pulley 127,
