A structural component in the form of a wide plate is to be fabricated from a steel alloy that has a plane strain fracture toughness of 88 () and a yield strength of 710 MPa (51490 psi). The flaw size resolution limit of the flaw detection apparatus is 4 mm (0.1575 in.). (a) If the design stress is one-half of the yield strength and the value of Y is 1.07, what is the critical flaw length

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Select any two (2) areas of applications of chain-drive. (clo4) a)-permanent lubrication necessary b)-hydraulic forklift truck operation c)-rigging and heavy moving materials d)-relatively high maintenance costs e)-costlier than belt drives

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
