15 Trace the movement of the crank and slotted lever mechanism using a Vdegree interval in the crank as reference. Given the crank rotates at a fix point B and the slotted bar rotates at a fix point A (point A, B and C are vertically aligned with each other). Also, measure the stroke length of the slider and write its dimensions. The dimesions and initial state of your crank and slotted lever mechanism is as follows: Parts (by color): Crank (blue) = 60mm Slotted Bar (green) = 350 mm Slider (yellow) = stroke length unknown Distances (by point): Point A-B = 90mm Point B-C = 90mm A

Crank Angle (Q) Slider Position(S) Position 1 0° 12 cm Position 2 90° 10 cm Position 3 120° 8 cm Once the mechanism is completed, ie r, L, e are found. Draw the mechanism at 0°,90° and 120° crank angles and measure x coordinate of slider, which is 5 , and check if the measured values are 12 cm, 10 cm , 8 cm. (Hint:Square root operation makes this problem difficult.You have to get rid of the square root sign. this we can do by leaving the square root term alone on one side of the equation and then squarring both sides.
