Final 13 - Double Inclined Plane
Given:
- $\mbox{Two masses connected by a rope and pully} $
- $\mbox{mass 1 is on a plane inclined at an angle alpha} $
- $\mbox{mass 2 is on a plane inclined at an angle beta} $
- $a = g \frac{M_{unknown}\sin{\beta} {(operator)} M_{unknown}\sin{\alpha}}{M_1 ({operator}) M_2} $
Question:
- $What are subscripts and operators? $
Rationale:
- $M_1 \; \mbox{is associated with angle alpha} $
- $M_2 \; \mbox{is associated with angle beta} $
- $a = g \frac{M_2 \sin{\beta} {(operator)} M_1 \sin{\alpha}}{M_1 ({operator}) M_2} $
- $\mbox{The denominator operator cannot be multiply or divide}$
- $\mbox{Since if either mass is zero, then the equation would be indeterminate} $
- $\mbox{So the operator must be + or - }$
- $\mbox{But it cannot be minus, since it would indeterminate is the masses are equal}$
- $\mbox{Therefore the denominator operator is plus.}$
- $\mbox{If the masses are equal and the angles are equal, }$
- $\mbox{Then the numerator must be zero}$
- $\mbox{Thus the numerator operator must be minus.}$
