An engine turns at 250 revolutions per minute and its stroke is 450 mm. Find the average piston speed in meters per minute, and the speed of the centre of the crank pin in meters per minute.

In the figure shown, If v=800 mm/s, solve for the (a) velocity (in m/h) of D and (b) the angular velocity (in rpm) of AB. 320 mm 100 mm B 100 mm D -240 mm

Two cylinders rolling in the opposite direction has a speed ratio of 3. If the diameter of the driver is 10 inches, find the center distance between cylinders.

A bicycle with 20-in.-diameter wheels has its gears set so that the chain has a 6-in. radius on the front sprocket and 4-in. radius on the rear sprocket. The cyclist pedals at 175 rpm.Find the linear speed of the bicycle in in/min (correct to at least two decimal places)    in/min

A shaft is uniformly accelerated from 10 rev/s to 18 rev/s in 4 seconds. The shaft continues to accelerate at this rate for the next 8 seconds. Therefore, the shaft rotates with a uniform angular speed. Find the total time to complete 400 revolutions.

Find all the velocities if distance is 4m and time is 5s

For a belt and 2-pulley system, the pitch diameters of the pulleys are 4 inches and 10 inches.  Larger pulley is the driver.  The center distance is 24 inches.  If the angular speeds of the smaller and larger pulleys are 250 RPM and 100 RPM respectively, determine linear velocity in ft/min.

two pulleys are connected by a belt. The nubers of RPM of the two pulleys vary inversely as their diameters. A pulley having a diameter of 25cm is turning at 900 rpm. what is the number of RPM of the second pulley wgich has a diameter of 40cm

use 4 decimal in the solution

A universal joint is used to connect two shafts which are inclined at 20° and the speed of the driving shaft is 1000 rpm. Find the extreme angular velocity of the driven shaft and its maximum acceleration.
