1.Given a type of material used in a wire with diameter (d = 0.25 in) that stretches 2.3 inches while 80 feet of length is under tensile load of 1800 pounds. Find the elastic modulus of the material used to construct the wire.
2.Oil of specific gravity 0.84 flows in the pipe shown in Fig. P3.34. If viscous effects are neglected, what is the flowrate?
3.Determine the magnitude of the couple force so that the resultant couple moment on the crank is zero.
