For the beam shown, (a) Determine the normal and shear stresses at point E. Point E is located 10 cm below the top of the beam and at section X-X in the middle of the beam shown. (b) Plot a stress element for the point E. (c) Find the principal stresses at point E (Analytical). (d) Draw qualitative Mohr’s circle for the stress element at E. (e) Plot qualitative Mohr’s circle for the principal stresses the maximum shear stress at point E.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

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.
