As the production planner for Xiangling Hu Products, Inc., you have been given a bill of material for a bracket that is made up of a base, 1 spring, and 4 clamps. The base is assembled from 2 clamps and 2 housings. Each clamp has 1 handle and 1 casting. Each housing has 2 bearings and 2 shafts. There is no inventory on hand. This exercise contains only parts b and c. The product structure is as follows: b) Determine the gross quantities needed of each item if you are to assemble 75 brackets. \begin{tabular}{lr} Base: & units (enter your response as a whole number). \\ Spring: & units (enter your response as a whole number). \\ Clamp: & units (enter your response as a whole number). \\ Housing: & units (enter your response as a whole number). \\ Handle: & 450 units (enter your response as a whole number). \\ Casting: & 450 units (enter your response as a whole number). \\ Bearing: & 300 units (enter your response as a whole number). \\ Shaft: & 300 units (enter your response as a whole number). \end{tabular} c) Compute the net quantities needed if there are 30 of the base and 100 of the clamp in stock. \begin{tabular}{ll} Base: & units (enter your response as a whole number). \\ Spring: & units (enter your response as a whole number). \\ Clamp: & units (enter your response as a whole number). \\ Housing: & units (enter your response as a whole number). \\ Handle: & units (enter your response as a whole number). \\ Casting: & units (enter your response as a whole number). \end{tabular} Bearing:Shaft:units(enteryourresponseasawholenumber).units(enteryourresponseasawholenumber).
