Question 8 A metal cutter is used to chop metal sheets. The length of the metal sheets is 10000mm the width of the metal sheet is 40mm and the thickness of it is 4mm. If the shear force of the metal cutter is 8kN. Calculate the shear stress of the material.
Answer the following problem. Show your complete solution. Use 4 decimal places. 2. Two shaft of diameter 50 mm are joined by a rigid flange coupling and transmit a torque in such a way that the shear stress in shaft does not exceed 100 N/mm2. If six bolts are used to join the flange and the bolt circle is 150 mm in diameter. Determine the diameter of the bolt if the permitted shear stress in the bolt is 80 N/mm2.

PLEASE WRITE YOUR COMPLETE SOLUTION AND BOX THE FINAL ANSWER. THANK YOU. A piece of wood used as a compression block as shown has a cross-sectional area equal to the shaded area. Determine the safe value of P that can be applied to the block if the compressive stress is limited to 26 MPa, the shearing stress parallel to grain is limited to 5.66 MPa, 6.67 MPa, and 7.76 MPa for 15°, 20°, and 25°, respectively, and the bearing stress between the bearing plate and the wood is limited to 17 MPa. The diameter of the circle is 27 cm. Assume that the area under shear is equal to the cross-sectional area divided by the cosine of the grain inclination.
A flanged bolt coupling is used to connect a solid shaft 85 mm in diameter to a hollow shaft 100 mm in outside and 85 mm in inside diameter. If the allowable shearing stress in the shafts and the bolts is 66 MPa, how many 10-mm-diameter steel bolts must be used on a 185-mm- diameter bolt circle coupling so that the coupling will be as strong as the weaker shaft? Round off the final answer to two decimal places.
A smooth plastic pipe is to be designed to carry 10 (ft^3)/s of water at 20°C (68°F) through 1750 ft of horizontal pipe with an exit pressure at 20 psig. The pressure drop is approximately -280 psig. Estimate the pipe diameter (in inches) that will result in the given pressure drop. For water at 68°F: p = 1.94 slug/(ft^3), and u = 2.09E-5 slug/(ft-s). Round your answer to 2 decimal places.
