Write a general an m-file to solve a system of linear equations by using cramer's rule. you should have in the argument (a, b, n), which (a) represents the coefficients , and (b) is a column vector that represents the right hand- side of the equations, and(n) represents the number of equations or the unknowns.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

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
