The state of stress at a point in a body is defined by the stress components = =− = =− and == consider a plane that passes through the point and has unit normal vector (1/10, 3/10, 3/10) relative to the x, y, z. (a) find the stress vector components of the x, y, z axes acting on the plane. (b) find the magnitude stress vector components of the x, y, z axes acting on the plane. (c) find the magnitude of the normal stress acting on the plane. (d) find the magnitude shear stress acting on the plane.

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

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.
