A Copper plate that is 588mm wide and 48 mm thick is to be reduced in a single pass in a two high rolling mill by using a 321mm diameter roll. The coefficient of friction at roll workpiece interface is  0.14 and the roll rotates at 107rpm. The rolling process is performed above the recrystallization temperature of the material and the width of the plate does not change during this operation. What is the minimum final thickness (mm) possible

A particle moves along a straight line with an acceleration a=2v1/2m/s2, where v is in m/s.

If s = 0, v = 1 m/s when t = 0, determine the time for the particle to achieve a velocity of 18 m/s. Also, find the displacement of particle when t = 1 s. Express your answer using three significant figures and include the appropriate units.

Consider 4 blocks with different masses mi connected by ropes of negligible mass.

use python.

Consider 4 blocks with different masses mi connected by ropes of negligible mass. Three of the blocks lie on an inclined plane and the fourth lies in the direction of the gravity vector. The coefficients of friction between the blocks and the inclined plane are µi. The equations of motion governing these four blocks are described by the following system of equations:

T1 + m1a = m1g(sin(theta) - µ1*cos(theta))

-T1 + T2 +m2a = m2g(sin(theta) - µ2*cos(theta))

-T2 + T3 + m3a = m3g(sin(theta) - µ3*cos(theta))

-T3 + m4a = -m4g

Where the Ti denote the tensile forces in the ropes and a is the acceleration of the system. Determine a and the three Ti for θ = 45°, g = 9.82 m/s2 , {mi} = [10, 4, 5, 6]^T kg, and {µi} = [0.25, 0.3, 0.2]^T

The output to the command terminal prompt within Spyder should read:

T1 =

T2 =

T3 =

a =

All values should be printed out to 4 significant digits of accuracy and units must be assigned.

1. Air enters a steady-state diffuser at T1 = 20 °C, P1 = 100 kPa
and leaves at P2 = 105 kPa. You may assume an adiabatic
diffuser and constant specific heats. Find T2 if:
a) V1 = 10 m/s, V2 = 0 m/s
b) V1 = 100 m/s, V2 = 90 m/s
c) V1 = 500 m/s, V2 = 490 m/s
d) V1 = 1000 m/s, V2 = 990 m/s

Hot combustion gases enter a gas turbine at 0.8 MPa and 0.538 m3/kg at a rate of 2.1 kg/s, and exit at 0.1 MPa and 2.29 m3/kg. Heat is lost from the turbine to the surroundings at a rate of 150 kW and the internal energy decreases 904 kW in the process. What is the power output of the gas turbine? (Assume no change in velocity or elevation across the turbine.)

In 1999, the 125 million dollar Mars Climate Orbiter crashed onto the surface of Mars due to a unit conversion mistake. Briefly research this story and write a short, one or two paragraph, explanation of the unit conversion error that caused the crash (make sure you use your own words and include the list of references that you used). Then, show the unit conversion that the engineers providing the information to NASA’s Jet Propulsion Lab (JPL) should have used to ensure that the values were in the correct units.
