A Beyblade is a commercial line of a toy tops. It is spun using a rack (ripcord) and a pinion gear inside the launcher. If the ripcord length is 270 mm and it leaves the launcher for 3 seconds and the diameter of the gear is 20mm.Find the rotational speed of the Beyblade top. If the Beyblade stopped rotating after 2 mins, what is the angular deceleration?
The engine mechanism shown in the figure below has crank OB = 50 mm and length of connecting rod AB = 225 mm. The center of gravity of the rod is at G which is 75 mm from B. The engine speed is 200 rpm. For the position shown, in which OB is turned 45° from OA, Find the following: a. velocity of G and the angular velocity of AB; and, b. the acceleration of G and angular acceleration of AB.
In the image on the right, there is a red gear G1 on the left with a radius of r1 = 2.81cm. Gear G1 is locked to the green gear G2 with a radius of r2 = 0.734cm. Gear G2 then shares the same axle as the blue circular saw G3, which has a radius of r3 known to make a full rotation every T = 0.836s. Using at least 6 significant digits in your calculations, compute the following: V3! 12.8cm. Gear G1 is W1 a) The angular speed wi of gear G1. Remember that angular speed is measured in radians per T3 r2 unit time. G2 b) The rim speed vi of gear G1. Since gears G1 and G2 are locked together, the rim speed of G2 is also v1. G1 G3 c) The angular speed w2 of gear G2. Since gear G2 and saw G3 share the same axle, the angular speed of G3 is also w2. d) The rim speed v3 of saw G3.
