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.

A classroom group studies a horizontal cart attached to a spring on an idealized low-friction track. For this calculation the spring is massless, the track is level, friction is neglected and the restoring law is linear over all displacements used.

A student places a hypothetical metal specimen into water in an insulated calorimeter. All numerical thermal properties are supplied for this exercise rather than inferred from a material name.

A theoretical direct-current source is modeled as an ideal electromotive force of 12.0 V in series with a fixed internal resistance of 1.0 ohm. Initially its external load is a 3.0 ohm resistor.
