Consider a beam traveling through diamond and impinging upon the diamond-air interface. the critical angle of incidence for total internal reflection to occur is closest to the following value: select one: a)-22.50° b)-23.85 c)-24.30 d)-23.40° e)-none of the above

Design a quick return four bar mechanism that will have time ratio of tr 1: 1.25 . the output link should scan 60° angle for a full crank rotation . the length of output link is 5.0 em 1)-find the length of the other links and draw the mechanism .(write down your steps) 2)-does the mechanism satisfy the grashof's condition. 3)-find the max and min transmission angles over the range of motion using graphical technique
