The shaft shown in Figure P11-4 was designed in Problem 10-19. For the data in row (a) of Table P11-1, and the corresponding diameter of shaft found in Problem 10-19,….
Determine the angular velocity (magnitude and direction) of link OCat the instant shown.
Link AB (2) of the mechanism shown in Figure Q1 has a constant angular velocity of co2= 2.5 rad/s. It has a pin at B which is confined to move within the slot of link OC (3).
Given: AB = 250 mm, OB = 780 mm, angle OBA = 30°
(a) Determine the angular velocity (magnitude and direction) of link OCat the instant shown. Use the method of instant centres. A graphical solution is acceptable (i.e., locate necessary instant centres to answer this question on Figure Q1). (b) Use relative velocity analysis to verify your answer (an) in (i) and to find the velocity of pin B relative to link OC. (c) Determine the angular acceleration (magnitude and direction) of link OC.
