For the electric saw shown in the figure, the saw can slide left and right on the horizontal bed where it is placed. Since the engine rotates the crank counterclockwise with a constant angular velocity of 60 dv/min, find the acceleration of the saw and the angular acceleration of the arm AB for the position where ?=90o.

2. Two rigid links are rotating in the horizontal plane as shown in the figure below. The left-most link rotates with angular rate ₁ of 4 rad/s. The end of the right-most link holds a pin which is confined to move along a slot in the other link. The length of the right-most link 72 is 0.45 m. Determine the angular rate ₂ of the second link at the instant shown. Use 0₁ = 30°, 0₂ = 60°, and r₁ = 0.6 m. 0

Find the acceleration of the translating piston at the given instant if w1 = 10 rad/s And a, = -5 rad/s² . Present a, vector 13 in. BAR 2 form. rad/s² az in/s² w1 = 10 rad/s a1 = -5 rad/s² -BAR 1

The rod AB, shown in the figure, can slide freely along the floor and the inclined plane. At the instant shown, the velocity of end A is 1.4 m/s to the left. (a) Show that the magnitude of the rod's angular velocity is 3 rad/s and indicate its direction. (b) Calculate the velocity of end B and express it in vector form using rectangular (Cartesian) components. 500 mm B 300 mm 125 mm
