Hooke’s Law defines the relationship between stress and strain. We also have a few other equations that relate stress and strain to other aspects of a material. where is stress, E is the elastic modulus, is strain, F is force, A0 is the cross sectional area, l is length, l0 is initial length, d0 is the initial diameter, and d is the diameter.

Determine the initial length, in mm, of the cylindrical sample given the following and save as prob03

E = 207 GPa d0 = 10.2mm F = 8900 N Δl = 0.25 mm

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
