For the position shown where @ =53°, point 4 on the sliding collar has a constant velocity of v-1.25 m/s in the direction shown. At this instant BD is horizontal and DE is vertical, a) Find the velocity of point D and angular velocity of link DE by using instantaneous center of zero velocity, b) Find the angular acceleration of link BD and DE. 00 mm 101 1Pomm

I'm trying to understand this problem is there an easier way to solve  other than the the solution I attached? That just doesn't look like a relative acceleration equation it is so complicated any help is so appreciated thanks.

A four-bar linkage is shown in the figure (the ground "link" OC is considered the fourth bar). If the angular velocity and angular acceleration of drive link OA are 6.1 rad/s and 6.6 rad/s² respectively, both counterclockwise, determine the angular accelerations of bars AB and BC for the instant represented. The angular accelerations are positive if counterclockwise, negative if clockwise. The answers are not 2.356 and 11.327.

The flywheel shown has an angular velocity of 600 rpm. The connecting rod AB slides through the pivoting collar at C. When 0= 45°, find @AB, the angular velocity of AB. Hint: The direction of the velocity of the bar AB at a point directly under C is parallel to the collar C. That direction can be found from trigonometry. A 16" B

= 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.

A portion of a steam locomotive is shown below. If the locomotive is moving to the right at a constant speed of 45 mph, (a) what is the linear and angular velocity of point B, and (b) what is the linear and angular acceleration of point B, given that the wheels are 50 inches in diameter, length AC = 10 in, length AD = 55 in, and B is half way between A and D.

Please solve using INSTANTANEOUS CENTER method, thank you :)

For the following mechanism, rod AB is pinned to the two disks at point A and point B, and the two disks roll to the left without slipping. if the length of rod AB, I= 2.4 m, and its angular velocity @ = 6.2 rad/s, determine the magnitude of the linear velocity of point B. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point and proper unit. (0.5 m 0.5 m No slipping No slipping Your Answer: Answer units

At the instant mechanisms is shown below, for the gear its angular velocity is 6rad/s counterclockwise and its angular acceleration is 5rad/s2 clockwise. For the position depicited in the figure, using the vector method only, determine a) The angular veleocity of link BD and AB B) the angular acceleration of link AB and  BD
