16-67. Determine the velocity of point A on the rim of the gear at the instant shown. 45° 0.75 t 3 ft/s 1.50 ft 4 ft/s

υο VA W= A r v B CC A gear sits between two moving racks. If the top rack moves at a velocity of v₁ = 0.85 m/s to the left and the bottom rack moves at a velocity of VB = 0.3 m/s to the right, determine the velocity at the center of the gear, the magnitude of the angular velocity of the gear, and the distance to the ICZV from point B. The gear has a radius of r = 0.08 m. m/s Select an answer rad/s Select an answer VB BY UBC Engineering

07. At a given instant the roller A on the bar has the velocity and acceleration shown. Determine the velocity and acceleration of the roller B, and the bar's angular velocity and angular acceleration at this instant.
