$($b$)$ An open belt drive connects two pulleys, having same diameter of $100$ mm $,$ on parallel shafts $1\mathrm{.}5$ m apart. The driver pulley runs at $1500$ rpm $.$ The flat belt has a material density of $\backslash (12\mathrm{.}5\backslash$mathrm$\{$~kg$\}/\backslash$mathrm$\{$m$\}^\{3\}\backslash ),$ and themaximum tension in it is not to exceed $720$ N $.$ If the coefficient of friction between the belt and pulley is $0\mathrm{.}4,$ and cross section area of the belt is $\backslash (320\backslash$mathrm$\{$~mm$\}^\{2\}\backslash )$;

a$)$ Calculate the maximum different of the belt tension $($ N $).$

Furthermore, if the creep occurs on the belt, and the modulus of elasticity of the belt is $\backslash (300\backslash$mathrm$\{$MN$\}/\backslash$mathrm$\{$m$\}^\{2\}\backslash )$;

b$)$ Find the velocity of the follower pulley $\backslash ((\backslash$mathrm$\{$m$\}/\backslash$mathrm$\{$s$\})\backslash ).$

c$)$ Determine the power that can be transmitted $($kW$)$
