If we change load/store instructions to use a register (without an offset) as the address, these instructions no longer need to use the alu. (see exercise 4.15.) as a result, the mem and ex stages can be overlapped and the pipeline has only four stages.4.23.1 [10] < §4.5> how will the reduction in pipeline depth affect the cycle time? 4.23.2 [5] < §4.5> how might this change improve the performance of the pipeline? 4.23.3 [5] < §4.5> how might this change degrade the performance of the pipeline? 4.24 [10] < §4.7> which of the two pipeline diagrams below better describes the operation of the pipeline’s hazard detection unit? why? choice 1: ldur x1, [x2, #0]: if id ex me wb add x3, x1, x4: if id ex..me wb orr x5, x6, x7: if id..ex me wbchoice 2: ldur x1, [x2, #0]: if id ex me wb add x3, x1, x4: if id..ex me wb orr x5, x6, x7: if..id ex me wb

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
