3. Assume a 2D plot of loss function is like a 'saw' (or sequence of Ws) "wwww" with the second valley is deeper than the rest (other valleys are of same depth) and the second hill (center hill of the first W) is marginally higher than other hills (other hills are of same height). To reach the global minima, what should be the appropriate beta value in Momentum with GD, assuming the current location is at the leftmost hill? Justify your answer. No marks without justification. Note: All other hyperparameters are constant. a. beta < 1 b. beta = 1 c. beta > 1 d. None of the above

Now determine the support reaction forces, internal shear forces and moments, then plot its internal shear force and moment diagram. f[N/m] L 1. Define the paramters, use L and f as the variables y X
The last one is RESIGN INACCURACIES this relates to the type of machine or the process used during printing; the printers have a low tolerance meaning that the final product or parts after printing looks different from the original design. It could be fixed but this will increase the time and cost of production.
