For Problems 5–19 through 5–28, design a crank-rocker mechanism with a time ratio of Q, throw angle of (Δθ4)max, and time per cycle of t. Use either the graphical or analytical method. Specify the link lengths L1, L2, L3, L4, and the crank speed.
Q = 1; (Δθ4)max = 78°; t = 1.2s.

a problem existed at the stocking stations of a mini-load AS/RS (automated storage and retrieval system) of a leading electronics manufacturer (Fig.1). At these stations, operators fill the bin delivered by the crane with material arriving in a tote over a roller conveyor. The conveyor was designed at such a height that it was impossible to reach the hooks comfortably even with the tote extended. Furthermore, cost consideration came into the picture and the conveyor height was not reduced. Instead, a step stool was considered to enable the stocker to reach the moving hooks comfortably. The height of the hooks from the floor is 280.2 cm (AD). The tote length is 54.9 cm. The projection of tote length and arm reach, CB = 66.1 cm. a) What anthropometric design principles would you follow to respectively calculate height, length, and width of the step to make it usable to a large number of people? b) What is the minimum height (EF) of the step with no shoe allowance? c) What is the minimum…
