- Design a crank-rocker linkage that will move the rocker link between two extreme positions 45 degrees apart. The rocker should take twice the time to moving in one direction that it takes moving in the other. If the fourbar linkage designed above is non-grashof, list two ways in which you would alter the design so that the crank is able to rotate.arrow_forwardIn the below figure a Double-parallelogram mechanism is shown. Here PQ is a single link. Calculate the mobility of the mechanism?arrow_forwardA crank-rocker mechanism is to be used to drive a ratchet mechanism. Using mathematics and specific illustrations, find the required crank length in inches required to generate this motion. The swing of the rocker is 35.0 from the vertical position in each direction. (Note: O2 is the crank pivot; O4 is the rocker pivot; C is the coupler-rocker joint; B is the coupler-crank joint). O2O4: 5.6 in.; lies in the horizontal plane O4C: 4.0 in.; mid stroke is verticalarrow_forward

- When faced with the choice between two operations that appear to be equivalent, what criteria does the linker employ?arrow_forwardIn an open belt drive, two sheaves have diameters of 5 in. and 12 in. Determine the center distance of a drive utilizing a 72-in. belt. Also determine the angle of contact over the smaller sheave. Draw a 3d model of the mechanism.arrow_forwardA four-part mechanism like this one, if it is known the length of o2a (link 2) is 5 cm (link 3) is 4 cm (link 3) and the length of the bo4 (link 4) is 5.5 cm (5 in.). At the a point working the p = 50 Newton style with the sustric orientation of the horizontal line is 20⁰, look for styles that are going on and torque on link 4.arrow_forward
- You have a lever, 2m on each side, and four masses: 5kg, 10kg, 15kg and 20kg. You will place the blocks at different positions on the lever such that the two sides balance. Place each block a unique distance from the fulcrum. Use a torque balance to prove the system will not move.arrow_forwardHi I was wondering if I could get help with the last three parts in this question to find the instant centers of the linkagesarrow_forwardFor the water spray mechanism in Figure P1.51, clas sify the four-bar mechanism, based on its possible motion, when the lengths of the links are a = 12in ., b=3 in. , c=12 in. , and d = 5inarrow_forward
