1Strain-Gauge Calibration: Least Squares After a Suspect Reading
A calibration technician records a strain gauge's output y (mV) at five known loads x (kN): (1, 2.10), (2, 3.95), (3, 6.10), (4, 7.85), (5, 10.20). The intended model is y = a + bx.

A 4.0 kg wooden block on a rough plane inclined at 25° to the horizontal is joined by a light string, passing over a small pulley at the top of the plane, to a 2.5 kg mass hanging freely. The coefficients of friction between block and plane are μs = 0.45 and μk = 0.35.

A student uses a plane transmission grating marked '500 lines per mm' and 10 mm wide to try to resolve the sodium doublet at 589.0 nm and 589.6 nm. A collimator produces a parallel beam that falls on the full width of the grating, and the diffracted light is observed through a telescope.
