Unformatted text preview: draw a velocity diagram. F in Scale 1:20 F out Page 3 of 6 Question 4 [25] A crankslider mechanism is shown below. The crank length is 30 mm. The length of the connecting rod is 110 mm. The offset between the centerline of the piston and the crankshaft is 15 mm. The crank rotates counterclockwise at a constant speed of 180 rpm. Part 1 (19) For an arbitrary crank position, determine (a) the (linear and angular) positions of the piston and the connecting rod, (b) the angular velocity of the connecting rod and the linear velocity of the piston, (c) the angular acceleration of the connecting rod and linear acceleration of the piston. Part 2 (6) Determine values of all quantities in (a), (b) and (c) for θ 2 = 60 ° . Not to scale. B A θ 3 r 3 ω 2 r 2 θ 2 r 1 s Page 4 of 6 Page 5 of 6 Page 6 of 6...
