A thin rectangular polymer plate PQRS of width b = 410 mm and height a = 154 mm is shown in the figure. The plate is deformed so that corner Q is displaced upward by c = 3.7 mm and corner R is displaced leftward by the same amount. Determine the shear strain at corner P after deformation. a ack R P b 2 S a X

1.) A.) A cutting operation is performed on a piece of metal. The rake angle of the tool, α, is eight degrees. The tool penetrates the work to a depth of 8mm. The chips generated from this cut are 20mm thick. Calculate the shear plane angle, Φ, in the orthogonal model for this operation. Give your answer in degrees B.) For the same cutting operation, the cutting and thrust forces are measured. The cutting force is measured as 1600N, and the thrust force is measured as 1300N. The width of the cut is 4mm. What is the shear stress applied by the tool? Give your answer in MPa.

ADVANCED CHEMISTRY! RATE WILL BE GIVEN! PLEASE WRITE THE COMPLETE SOLUTIONS A Steam at 400 deg C an 8,200 kilo Pascals enters a turbine and leaves at 10 kPa. What is the entropy of the leaving steam if the efficiency of the turbine is 0.76. Round the answers in to 2 decimal places. Hint: Turbine's efficiency is the ratio of work delivered by the actual turbine to the work delivered by an isentropic turbine (no entropy change)   H (kJ/kg) S (kj/kg-K) 8200 kPa, 400 degrees 3137.6 6.3534 10 kPa, sat. liquid 191.832 0.6493 10 kPa, sat. vapor 2584.8 8.1511

Question 6 a) The bore of each cylinder in a six-cylinder car engine is 45 mm and the stroke for each piston is 125 mm. calculate the cubic capacity of the engine in cubic centimetres (cm³); and calculate the clearance volume per cylinder for a compression ratio, r, of 8.75. b) The bore of each cylinder in a four-cylinder four-stroke internal combustion engine is 38 mm and the stroke of each piston is 165 mm. During testing, the engine runs at 180 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 3.4 cm² and a diagram length of 1.2 cm. The pressure scale on the indictor diagram is set to 150 kN/m² per cm. Calculate the mean effective pressure (m.e.p) and the indicated power developed by this four-cylinder four-stroke engine. c) Figure Q6c shows a pulley system with a suspended load w of 2000 N. Calculate the following: (i) (ii) (iii) (iv) The effort force (FEffort) necessary to lift and hold a load of 2000 N. The ideal mechanical advantage…
