Explanation Given data: Unit of length, 1 stride = 1.5 meters , Unit of time, 1 blink = 0.3 seconds , Unit of mass, 1 heavy = 5 kilograms , and The given expression is, 1 N = X heavy stride ( blink ) 2 (1) Calculation: Equation (1) can also be written as follows. 1 newton = X × 1 heavy × 1 stride ( 1 blink ) 2 Consider the LHS of the equation (1). N in SI unit can be expressed as kgm s 2 . Therefore, 1 N = 1 kg ⋅ m s 2 (2) Now, 1 stride = 1.5 m Therefore, 1 m = 1 1.5 stride 1 blink = 0.3 s Therefore, 1 s = 1 0.3 blink 1 heavy = 5 kg Therefore, 1 kg = 1 5 heavy Substitute 1 5 heavy for 1 kg, 1 0

An AISI 1018 steel ball with 1.100-in diameter is used as a roller between a flat plate made from 2024 T3 aluminum and a flat table surface made from ASTM No. 30 gray cast iron. Determine the maximum amount of weight that can be stacked on the aluminum plate without exceeding a maximum shear stress of 19.00 kpsi in any of the three pieces. Assume the figure given below, which is based on a typical Poisson's ratio of 0.3, is applicable to estimate the depth at which the maximum shear stress occurs for these materials. 1.0 0.8 Ratio of stress to Pmax 0.4 90 0.6 στ Tmax 0.2 0.5a a 1.5a 2a 2.5a За Distance from contact surface The maximum amount of weight that can be stacked on the aluminum plate is lbf.
