A mechanism is shown in the following figure. Link ABC has an arc slot with a radius of R =100mm . The center of the arc O1 is on the line BC. The crank OA has a length of 100 mm. It rotates about point O with a constant angular velocity of ω =4 rad/s. Find: I) Equation of motion of the link ABC and 2) The velocity and acceleration of link ABC when phi= 30 degree.
Assume that you have an object that you want to image onto a viewing screen 1500mm away from the object. What are the possible image magnifications if you image the object onto the screen with a thin lens of focal length f=160mm? What focal length..
