2. Refer to the following sequence of instructions, and assume that it is executed on a 5-stage pipelined datapath. add r5, r2, r1 lw r3, 4(r5) lw r2, 0(r2) or r3, r5, r3 sw r3, 0(r5) a. If there is no forwarding or hazard detection, insert nops to ensure correct execution. [3 pts] b. If the processor has forwarding, but we forgot to implement the hazard detection unit, what happens when this code executes? [2 pts]

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
