Estimate the assembly efficiency for each design

Reference no: EM131407183

A spindle-bracket assembly uses the following parts: a steel spindle, two nylon bushings, a stamped steel bracket, and six screws and six nuts to attach the nylon bushings to the steel bracket, and thereby support the spindle. Com pare this assembly with the spindle-bracket assembly shown in Problem 16.65, and estimate the assembly efficiency for each design.

Problem 16.65

The design shown in Fig. P I6.65 is proposed for a metal tray, the main body of which is made from cold-rolled sheet steel. Noting its features and that the sheet is bent in two different directions, comment on various manufacturing considerations. Include factors such as anisotropy of the rolled sheet, its surface texture, the bend directions, the nature of the sheared edges, and the way the handle is snapped in for assembly.
