Homework $9-$ Please plot in the requested units $($i$.$e$.$ Nm versus RPM$,$ or HP versus RPM$].$ Only up to

$50\%$ credit will be provided in the plots are not in the requested units. Plots must be professionally

prepared with appropriate legends, scaling ets.... Follow all instructions below. Please include your

Matlab code $($or other$)$ as a neatly prepared appendix to your submission, which needs to be a single

$.$PDF$.$ Do not send separate files or your $.$m files.

$(1)$ Reproduce Figure $9\mathrm{.}5$ in the text book $($Torque $[$Nm$]$ versus RPM$),$ using the parameters in $(10\%).$ You

need to utilize MATLAB or code of your choice to recreate the plot. Use the exact same scaling as in Fig.

$(2)$ For the same conditions plot the same information but plot Shaft Power $[$HP$]$ versus RPM$.(10\%).$ Use

the same scaling for the x$-$axis as in Fig.

$(3)$ Plot $($Torque $[$Nm$]$ versus RPM$)$ ON THE SAME PLOT for three cases with Xrated $=220$V$,$ but at

frequencies of $50,60,70$Hz$.$ Only plot for positive RPM and positive torque$(40\%)$

$(4)$ Plot $($Power $[$HP$]$ versus RPM$)$ ON THE SAME PLOT for three cases with Xcated $=220$V$,$ but at

frequencies of $50,60,70$Hz$.$ Only plot for positive RPM and positive torque $(40\%)$
