Question: Problem 2: Design of a Scissor Jack The figure below shows a schematic of a vehicular screw jack. The jack is to be designed to safely carry maximum mass of 500 kg. The design should allow the link angle to vary from 15 to 70°. The lengths of the links are 300 mm long. a) Estimate the maximum amount of tensile load that the screw ...
8.Three concentric spherical shells have radii a, b, and c(a b c) and have surface charge densities , and respectively.If VA, VB and VC denote the potentials of the three shells, then, for c = a + b, we have : (1) VC = VB = VA (2) VC = VA ≠ VB (3) VC = VB ≠ VA (4) VC ≠ VB ≠ VA
Here’s the best way to solve it. The following equation is the entropy balance equation for an open system dscy -F2 +<**: -Ekoso+0cv dt e Simplify the above equation for a control volume with a single inlet and two outlets, and adiabatic in the CV.
Equation 3.4.1 is called the Sum of Squared Errors (SSE). Using calculus, you can determine the values of a and b that make the SSE a minimum. When you make the SSE a minimum, you have determined the points that are on the line of best fit. It turns out that the line of best fit has the equation: ˆy = a + bx.
