1 of 1 3. A four-bar linkage is shown below. (A) the directions of each. (B) E on link 3. Use the method of velocity vector polygons to calculate w, and wq. Report Find and report the magnitude and direction of the absolute velocity of point RAD = 10 cm, Rap = 15 cm, Ra = 60 cm; R = 65 cm; Rp = 15 cm W2 = 2 rad/s cw (Note: ADB and FEC are right triangles.) link 3 A. link 2

need urgent help please also i need the coordinate system for each joint thanks in advance

Hi, I have an engineering dynamics question.

The reason I am asking it is because it is a hard question that I need help with

Please i need her solve

The link length and value of O2 for some four bar linkages are defined below, (fixed link =12 cm, drive link =5 cm, coupler link = 10 cm, follower link= 8 cm) 1. draw the linkage to scale and graphically find all possible solution (both open and cross) for 03 and O4, analytical . 2. If w = 2 rad /s (CCW) find the angular velocity for bar 3 and 4 3.if a= 5 rad/s² (CCW) find the normal and tangential acceleration for link 3 and 4

A four-bar mechanism is used to transmit power to slider E. Link AC rotates counterclockwise at 100 rpm. A and B are fixed points. The following linkages are measured in cm: AC=35, AB=70, CD=45, BD=45, DE=40. Find the instantaneous velocity of slider E in cm/s 1.Draw the mechanism in appropriate scale on your paper2. Find the instantaneous linear velocity of C3. Find a point on your paper to draw the velocity polygon and scale the magnitude of the computed linearvelocity4. Use the relative velocity equation for finding the linearvelocity of D; ? = ? + ?? ? ?/?5. Remember that although the magnitudes are unknown, their directions can be identified6. Obtain the magnitudes of the unknown velocities from the velocity polygon7. For Link DE, repeat the process by using ? = ? + ??the line as much as needed8. Remember that E is a SLIDER therefore it can only goin the direction where its movement is not constrained? . Add the vector ? to the head of ? and extend?/? ?/??

Pls i need her solve with explanation
