Task 1 - Bar Mass Apparatus: Method I Find the angular acceleration of the apparatus. $?=$ ${?}^{?}\mathrm{rad}/{\mathrm{s}}^2$ Find the acceleration of the hanging mass. $a=$ ${?}^{?}\mathrm{m}/{\mathrm{s}}^2$ (Hint: same as tangential acceleration of the hub where the string is wound) Find the tension force in the string ${\mathrm{F}}_{\mathrm{T}}=?\mathrm{rad}/{\mathrm{s}}^2$ Hint: draw a FBD - Note: $F_T?=m{h}^{?}g$ Find the torque on the apparatus $?=$ $\mathrm{Nm}$ Find the rotational inertia of the apparatus I = ${\mathrm{kgm}}^2$ Method 2 Given the mass of the bar $\mathrm{mb}=823\mathrm{g}$, the length of the bar L $=85.1\mathrm{cm}$, the mass of the two cylinders $\mathrm{M}=$ $2.79\mathrm{kg}$, and the distance between the two cylinders $D=80.0\mathrm{cm}$ Find the rotational inertia of the bar ${\mathrm{I}}_{\mathrm{b}}=$ ${\mathrm{kgm}}^2$ Find the rotational inertia of one mass $l_M=$ ${\mathrm{kgm}}^2$ Find the rotational inertia of the entire apparatus I = ${\mathrm{kgm}}^2$ Note: The results of the two methods should be equal but because the input numbers are randomly generated the results will not agree exactly
