For the mechanism composed of the discs A and B, and the BCD bar; Find the angular velocity of disk A and the velocity of point D. From the table, use the values ​​in the last row for the velocity of point C and the distances and angle marked in the image. Notes Discs A and B have a non-slip contact. Point C is bolted to the yellow collar and bar B. The movement of the collar is defined by the gray bar, which is fixed. The bolt allows the BDC bar to rotate at that point. The BCD bar is a single rigid body

The elements of a power hacksaw are shown in Figure 2. The saw blade ismounted in a frame that slides along the horizontal guide. If the motor turns the flywheel at a constant counter-clockwise speed of 60 r.p.m. Make use of vector diagram to calculate: the acceleration of the blade for the position where angle ? = 90o The corresponding angular acceleration of the link AB.

In the figure, Pulley A, rotating at 20 rad/s, controls the motion of Pulley B. The motor of pulley A is cut off, and friction eventually brings the pulleys to a stop with an angular acceleration of α = -2.5t rad/s2. If there is no slippage, determine: a. The angular velocity of B with respect to time b. The angular displacement of B during the deceleration c. The acceleration of point C with respect to time

Bar OC rotates with a clockwise angular velocity woc = 5.3 rad/s and a counterclockwise angular acceleration doc = 4.6 rad/s². The bar OC is a slotted member which accommodates the pin A attached to the sector. Determine the angular velocity w and the angular acceleration a of the sector. The angular velocity and the angular acceleration are positive if counterclockwise, negative if clockwise. Assume OA = 500 mm, d = 385 mm, 0 = 21°. Answers: W = B a = i i d aoc rad/s rad/s² @oc

In the mechanism shown below, the wheel is pinned at the center. The radius from O to C is 0.2 m and link CB is 0.55 m long. CB makes an initial angle of 25° with the horizontal as shown. The hydraulic ram at B is moving left at 7 m/s. At the moment shown, what is the angular velocity of link BC and the wheel pivoted at 0? 0000 Ninbet tatis rad/s

I need all answers please

The mechanism below has a crank that revolves clockwise at point O at a speed of 2000 rpm. Using vector diagrams, determine: a) The linear velocity of the piston and the angular velocity of the link AB about A. b) The angular acceleration of the link AB about A and the inertial resistance produced by the piston. c)Using trigonometry, confirm your results for the velocity in parts (i), explain your reasons behind which method is preferable, and identify the error margin for your velocity answers.
