AEM 264-003/901 Homework #15 3/26/07 Due: Friday, 3/28/07 The six-step solution method, correct units and a reasonable number of significant digits (generally 3 or 4) are required for every problem solved in every homework assignment in this section of AEM 264. 1. The crankshaft rotates in the counter-clockwise (CCW) at 3200 RPM. The length of the crank offset from A to B is 2.0 inch. The length of the connecting rod from B to C is 4.0 inches. Draw this system full scale (either by hand or AutoCAD) and find the angular velocity of link BC by instant centers . If the angular acceleration of link AB is -10 rad/s 2 , what is the angular acceleration (magnitude and direction) for the connecting rod BC at the given position? What is the linear acceleration of the piston at C?

If the velocity of point B is 26 inch/sec upwards, and the acceleration of point B is 10 inch/sec 2 downwards and the length of the bar AB is 37 inches, • find the linear velocity of point A and the angular velocity ω of the bar. • find the linear acceleration of point A and the angular acceleration α of the bar. 3. The angular velocity of link CD is a constant 4.0 rad/sec. Find the angular velocities, AB ω and BC using instant centers . Find the angular velocities, AB α and BC using equations . from Engineering Mechanics: Statics and Dynamics by R.C. Hibbeler, MacMillan, 1974 Note – points A and D are at the same vertical location. Link AB is 12 inches long. 35° ω i v v A A r r = j v v B B r r = A B o 45...
