Instantaneous Center Method—Analytical For the reciprocating saw shown in FigureP6.21, use the instantaneous center method to analytically determine the linear velocity of the blade as the crank wheel rotates counter-clockwise at 1375 rpm Ans. 91.11 in/s

For the simple gear train below, Gear A is the input gear and rotates at 2500 rpm and Gear D is the output gear for this simple gear train. The number of teeth for each gear is as follows: NA = 116 Teeth, NB = 178 Teeth, NC = 70 Teeth and ND = 120 Teeth %3D %3! Calculate the output angular velocity at Gear D (WD). Give your answer in rads-1 to the nearest radian. Gear D Gear A Gear D Gear Input Gear A (2500 rpm) Output Gear D

3 Problem 1: A 20-in control rod ABC is attached to two slider blocks A and B. For the position shown, the velocity of B is 24 in/sec directed to the right. 8 in.- a) Using the method of Instantaneous Center of 20° 30 ° Revolution, determine the angular velocity of the rod. b) Determine the velocity of point A c) Determine the velocity of point C 12 in,

A flywheel drives a collar via link. The flywheel rotates at an angular velocity of 18 rad/sec clockwise. For 25° 2 Using ICR, determine: (a) the angular velocity of the link, (b) the velocity of the collar. d₁ = 75 mm d₂ = 260 mm NOTE: this is the same problem from this homework. but you must solve using ICR for B

15.28 In the position shown, the crank AB rotates with wAB= 10 rad/s counterclockwise. Suppose B' is the point CD coinciding with the pin at B. (a) Is the component of vB of the pin at B in the direction perpindicular to the slot equal to vB'? (b) Determine vD at the point D.
