Problem 5: Load cell design You are designing a load cell (force measurement device) based on the design shown below. Two plates are connected by two semicircular beams. Each beam has an outer radius \( R_{o} \) of 80 mm , thickness \( t \) of 5 mm , and width (into the page) of 10 mm . The beams will be made of aluminum 7075-T6. a) What is the rated load \( F_{R} \) ? The rated load is the maximum allowable force \( F \) for a safety factor of \( n=2 \) against yielding. b) If you can only use one Wheatstone bridge, how many strain gauges would you use, and where exactly would you place and orient them on the load cell for maximum sensitivity and selectivity? A and B only
