The angular velocity of link AB is wAB = 6.5 rad/s. Link CBis horizontal at the instant shown. R50 mm S00 mm 60 Part A Determine the I and y components of the velocity of the collar at C. Express your answers using three significant figures separated by a comma. ANSWER: Vz, Vy = m/s Part B Determine the angular velocity of link CB at the instant shown measured counterclockwise. Express your answer using three significant figures. Enter positive value if the angular velocity is counterclockwise and negative value if the angular velocity is clockwise. ANSWER: WCn = rad/s

= A) Knowing that angular velocity of link AB is WAB 4 rad/s, determine the velocity of the collar at C and the angular velocity of link CB at the instant shown. Link CB is horizontal at this instant. 45° WAB = -350 mm 4 rad/s Figure 1 B 500 mm b) Recently, there have been some concerns raised about the door opening system's safety, as it operates at a relatively fast speed, posing a serious hazard for people using wheelchairs. As a co- op student working with the door manufacturing company, your task is to propose a modification to the Linkage system of CBA that allows the door to open and close more slowly, ensuring that point C moves at a reduced speed. Providing a more comfortable and secure experience for individuals, including those using wheelchairs. Note: You may use further calculations or just use your steps in part A to suggest a change and justify it.
