Functional Requirements

This section provides the functional requirements, the tasks and behaviours that the software is expected to complete.

Input-Values: Input the values from Tab:ReqInputs.

Verify-Input-Values: Check the entered input values to ensure that they do not exceed the data constraints. If any of the input values are out of bounds, an error message is displayed and the calculations stop.

Calculate-Angle-Of-Rod: Calculate the following values: ${θ_{1}}$ and ${θ_{2}}$ (from IM:calOfAngle1 and IM:calOfAngle2).

Output-Values: Output ${θ_{1}}$ and ${θ_{2}}$ (from IM:calOfAngle1 and IM:calOfAngle2).

Symbol	Description	Units
${L_{1}}$	Length of the first rod	${\text{m}}$
${L_{2}}$	Length of the second rod	${\text{m}}$
${m_{1}}$	Mass of the first object	${\text{kg}}$
${m_{2}}$	Mass of the second object	${\text{kg}}$
