The wrench blanks, and the final wrench produced with the CNC machine, will be made from 6061-T6 aluminum alloy. With a factor of safety of 2, determine (i) the maximum force that can be applied to the handle, and (ii) the maximum torque produced by the wrench in tightening a bolt, both before yielding will occur. Draw a FBD of the wrench when you do the calculations.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
