Awire has been installed without proper strain relief. the 10-gauge, insulated, solid copper, electrical wire has been supporting a direct tensile load of about 50 pounds for several weeks. strain relief has been added to remove the load; however, your coworker needs to know if the wire needs to be replaced immediately. should the wire be replaced? show the support of your answer.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

Most leaks in reciprocating air compressors can be detected and minimized by: (clo4) a)-detecting leakage areas using ultrasonic acoustic detector. b)-tightening joints and connections c)-replacing faulty equipment d)-all of the given options

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
