A second class lever is used to lift a 600 lb load. The length from the fulcrum to the center of the load is 9 ft. The length from the fulcrum to the effort is 16 ft. What is the ideal mechanical advantage of the system?

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Write a technical essay (maximum two pages) about stress concentration. and paste from the textbook. instead, read updated material about this phenomenon and provide a technical evaluation of the different techniques to avoid/reduce such phenomenon. consider in your analysis cutting-edge computational techniques such as fea to study and analyze stress concentrations.
