2- The attached figure shows a power hacksaw used to cut metal. Link 5 pivots at O5 and its weight forces the saw blade against the workpiece while the linkage moves the blade (link 4) back and forth on link 5 to cut the part. It is an offset slider-crank mechanism. The dimensions are shown in the figure. For one revolution of driving link 2 of the hacksaw mechanism on the cutting stroke, find and plot the horizontal stroke of the saw blade as a function of the angle of link 2.
d = 170
3- For the mechanism shown in the figure, r = 30mm, r = 110mm, r = 120mm, rg = 150mm, OP = 100mm, AC = 60mm, and rs = 130mm. OO = 90mm. Find the angle of link 8. Input angle link 2 is 30 degrees.
