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 1 clamp and 1 housing. Each clamp has 1 handle and 2 castings. Each housing has 2 bearings and 1 shaft. There is no inventory on hand. This exercise contains only parts b and c. The product structure is as follows: Bracket Base (1) Spring(1) Clamp (1) Housing (1) Clamp (4) Handle (1) Casting(2) Bearing(2) | Shaft1) Handle (1) Casting (2) b) Determine the gross quantities needed of each item if you are to assemble 125 brackets. 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). OOOOO b) Determine the gross quantities needed of each item if you are to assemble 125 brackets.
