In pure rotation, what is the velocity (in m/s) of a point on the edge of a gear with a diameter of 50mm rotating at 7 rad/s?
I need 5-8 please QUESTION 4 What is the angular velocity if the tangential velocity is 20.1 m/s and the radius of rotation is 1.1 m (to one decimal place). QUESTION 5 What is the tangential velocity if an object is rotating at 302 degreests and has a radius of rotation of 1.7 m (to one decimal place)? QUESTION 6 Calculate the tangential velocity if the angular velocity is 8.1 rad/s (in reality the units are /s) and the radius...
A body is experiencing a translation of {10 i} m/s and a rotation of {2 k} rad/s. What is the magnitude (in m/s) of the velocity of a point located at a position of {5}}m relative the center of rotation?
A 3.9-m-diameter merry-go-round is rotating freely with an angular velocity of 0.80 rad/s . Its total moment of inertia is 1350 kg⋅m2 . Four people standing on the ground, each of mass 68 kg , suddenly step onto the edge of the merry-go-round. What is the angular velocity of the merry-go-round now?
A body is experiencing a translation of {10 i} m/s and a rotation of {2 k} rad/s. What is the magnitude (in m/s) of the velocity of a point located at a position of {5 j} m relative the center of rotation?
1. A rotating top has a scratch 0.05 m from the vertical axis of rotation. It does 3 revolutions in 5 seconds. The angular velocity of the top is rad / s. The tangential velocity of the scratch is m / s. Give your answers to two decimal places. 2. A skater is spinning at 2 rev / s. She increases her angular velocity in 7 seconds until it is 8π rad / s. By what angle, in degrees, does...
#2-8. Velocity of a rotating particle A point is currently at position x --4 m y -5 m, z 5 m and is rotating about the origin with angular velocity i k rad/s What is the velocity v of the point? k m/s
At the instant represented, the velocity of point A of the 2.06-m bar is 3.1 m/s to the right. Determine the speed Va of point B and the magnitude of the angular velocity w of the bar. The diameter of the small end wheels may be neglected. 0.52 m 59° BC 2.06 m А VA Answers: Va = m/s rad/s
A wheel of diameter 0.3 m is rotating with an angular velocity of 3 rad/s and slowing under a constant acceleration of -3 rad/s2. Calculate everything possible about the motion, starting with, say, its angular velocity after 0.4 s.
A 4.5-m-diameter merry-go-round is rotating freely with an angular velocity of 0.84 rad/s . Its total moment of inertia is 1700 kg⋅m2 . Four people standing on the ground, each of mass 68 kg , suddenly step onto the edge of the merry-go-round. What is the angular velocity of the merry-go-round now? What if the people were on it initially and then jumped off in a radial direction (relative to the merry-go-round)?
