Reading Material (Mechanics of materials, Beer 5th Edition):
Chapter 7 Section 10-13 Objective: Determine the strains and shear strains of a plane strain element. Concepts: Plane Strain Problem: Units: millimeters The cantilever beam shown above is subject to a load P acting at the mid -height of the beam at an angle alpha.
Two strain gages are mounted on the beam at point C (C is also at the mid-height).
Gage A measures the horizontal strain, and gage B measures the normal strain at an angle of 60º ea=125x10-6 . -6 and eb= -375x10 . Knowing that the beam is made of steel (E=200 GPa and ?=1/3), a) Determine the force P and the angle alpha.
b) Determine the principal strains and the orientation of the principal planes at C.
c) Determine the principal stresses at C. Bonus: What is the change in the thickness of the plate?
What is the volumetric efficiency
HEAT TRANSFER PROBLEM NO 2O- The hot fluid flows through a well mixed stirred tank which is provided with a cooling jacket . the fluid in cooling jacket can also be assumed to be well mixed . what is the heat transfer area of the jacket required?
Calculate the energy required to heat 1kg of CO 2 from 400ºC to 600ºC at a constant pressure of 1atm using:-
HEAT TRANSFER PROBLEMS NO16- Water flowing in a steel pipe of diameter 0.02 m is to be cooled from 40 to 30 oc . The velocity of water in the steel pipe is 1.5 m/s .
A string of negligible diameter is drawn down the center-line of a pipe containing a Newtonian fluid. At what velocity, w, must the string be drawn in order to vaporize the fluid?
Question -4 following gas phase reaction takes place at 500oc 4PH3 (g) ----( P4 (g) +6H2 (g) With rPH = 85h^-1*CPH3 What is the volume of the plug flow reactor operating at this temperature and 5.5 atm, giving 80% conversion for a feed of 2.5 kg-mol..
acetyl chloride is a colorless fuming liquid used primarily in the chemical industry.a how is acetyl chloride produced?
PART - A . Using the following data, draw up a heat balance for a steel ingot soaking pit for a twenty hours test period during which 130 tons of cold steel ingots were heated from 20 oc to 1220oc.
The addition of an oxidizing agent such as chlorine water to a clear solution of an unknown compound results in the appearance of a brown color. When this solution is shaken with the organic solvent, methylene dichloride, the organic solvent layer..
A large CSTR, small CSTR and PFR of fixed volume are available. In general, how wouldyou arrange them for getting maximum conversion forreactions of order >1 and1 arrangement is PFR followed by small CSTR followed by large CSTR tomaintain the reac..
Consider an engine that operates at a low temperature of 25C and a higher temperature of 432C. Would it be possible to have an efficiency of 65% ?
The liquid-phase irreversible reaction A ? B is carried out in a CSTR. To learn the rate law, the residence time, t is varied and the effluent concentrations of species A are measured.
