Two cylinders rolling in the same direction has a speed ratio of 4.2. If the diameter of the driven cylinder is 29 inches, find the diameter of the driver and the center distance between cylinders. DRIVER DIAMETER: CENTER DISTANCE:

The planetary gear train shown in the image below has 16 teeth on the sun and 22 teeth on the planet. The ring is driven by a motor at a speed of 100 revolutions per minute. The sun is stationary. What is the speed of the arm (planet carrier) in units of revolutions per minute? 5 Sun gear Ns 2 Arm --3-- Planet gear NR Np 4 Ring gear 0

The drum of a winch system is rotating at 294 RPM and the drum has a diameter of 8 inches. What is the linear speed at the surface of the drum in feet/sec? This is the same speed at which the cable of the winch is pulled in.

Shaft A with 9 inches diameter cylinder running at 190 rpm is connected to shaft B by means of 24 inches diameter cylinder. Another cylinder on shaft B, 14 inches in diameter, is connected to 10 inches diameter cylinder on shaft C. Find the speed of shaft C. SPEED OF SHAFT C:

For items 4-5, consider the slider-crank mechanism shown. Crank AB is 0.500 m long. Rod BD is 1.500 m long. The velocity at point B is 0.500 m/s, ↖45.0°. Which of the following gives the closest value to the speed of the piston at D? Which of the following gives the closest values of the lengths of the sides of the triangle formed by points B and D and point C, the instantaneous center of rod BD?

Please don't give stupid answer read the question carefully. Clarify whether the answer is 2/3 or 3/2.

A 500lb cart with 4 wheels having a diameter of 10 inches the cart is driven by a motor producing a torque of 19.56 ft.lb at 2500 RPM what is the acceleration produced.

A child rides his bike at a speed of 5ft/s. The dimensions of the tire and sprockets are given below. D₁ DIS Diameter of tire, D₁ = 22in Diameter of rear sprocket, Drs = 2.75in Diameter of front sprocket, Dfs = 6.5in Diameter of crank, Dc = 10in V a. How fast is the rear wheel spinning in rad/s? b. How fast is the crank spinning in rad/s? X Bogo Note: This isn't an image I generated, and you may find that velocity vector near the bottom misleading. I wouldn't have drawn it Dimensions: c. How fast are his feet moving in ft/s relative to the bike frame? Dfs De BY NO SA 2020 Joe Graber

A straight tooth spur pinion has a 19 tooth pinion rotating at a speed of 1640 rpm. The driven gear will be rotating at a speed of 480 rpm. If the module of the pinion is 2,5 mm and pressure angle is 25 degree; Evaluate the outer diameter (mm) of the gear.
