A stress of 2.8 MPa is applied in the [001] direction of a unit cell of an FCC copper single-crystal. Calculate the resolved shear stress on the plane in the [ 0 1 ¯ 1 ] direction. (This is the same as 7.4 just in a different direction with a different load). Give the answer in MPa with 2 decimals of accuracy.

In a load, the load is paralel to the shaft. n a. angular n b. thrust n c radial n d. none of the above

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

An ideal polarizer with its transmission axis rotated 30 degrees to the vertical is placed in a beam of unpolarized light of intensity 10w/m^2. after passing through the polarizer, what is the intensity of the beam? a. 8.7 w/m^2 b. 7.5 w/m^2 c. 5.0 w/m^2 d. 10 w/m^2 e. 2.5 w/m^2
