Solve and Draw the following. [Tech pen (0.2 light, 0.4 medium, 0.6 above heavy)] Consider a four bar linkage with the following links: L0 = 180mm, L1 = 40mm, L2 = 170 mm. Using grashof criterion, determine the ranges of values for L3 if the linkage is: a) crank-rocker mechanism b)drag link mechanism c) double rocker.

Position Analysis of the crank-slider linkage. The link length and offset for a fourbar slider-crank linkage are: link 2= 3.5, link3= 10, offset=1. Find both open and crossed solutions for angle theta3 and slider position, d, as driver makes a complete revolution.construct graphs to describe how the slider and theta3 varies as theta2 makes the entire revolution.

A general fourbar linkage configuration and its notation are shown in Figure below. The link lengths, coupler point location, and the values of 02 and w2 for the same fourbar linkages as used for position analysis in Chapter 4 are redefined in Table below. For the row c, draw the linkage to scale and Using an analytical method calculate w3 and w4 and find the velocity of point P. find the velocities of the pin joints A and.

1. Design a crank-rocker linkage that will move the rocker link between two extreme positions 45 de apart. The rocker should take twice the time to moving in one direction that it takes moving in the other. somyb\\; eqrad no malieb uroy dont elle est sor oldnoba mare ono mol foque (do iliw now wodor 00. aasbois.oved nov 2. If the fourbar linkage designed in question 1 is non-grashof, list two ways in which you would alter the design so that the crank is able to rotate.
