A sine bar is a precision measuring tool used to set and measure angles. It typically consists of a hardened steel bar with two accurately machined cylindrical rollers at each end, spaced a specific distance apart, usually 5 inches or 10 inches. The angle is determined by the height of a gauge block placed between the rollers, following the sine formula: sine(θ) = opposite (height of gauge block) / hypotenuse (distance between rollers). Sine bars are commonly used in machining and metrology for achieving precise angular measurements.
