WHP02-Q1 The slider block has a velocity of 2 m/s in the direction shown. The wheel rotates in the vertical plane about the fixed axis at C. When ACD is in the horizontal position and BD is in the vertical position, determine: (a) the magnitude and direction of the angular velocity of the wheel at this instant, and (b) the magnitude and direction of the angular velocity of link AB at the instant shown. Use the instant centre method to solve (a) & (b). 150 mm AC CD 150 mm D DB 400 mm B 400 mm VB = 2 m/s Answers: (a) = 10 rad/s CCW; (b) AB 5 rad/s CCW Week 2 Q a) 13 June 2023 20:14 WHP02-Q1 The slider block has a velocity of 2 m/s in the direction shown.
