To study a transient process, a model is constructed at a 1:10 scale. Water is used in the prototype, and it is known that viscous forces are the dominant ones. Compute the time, velocity, and force ratios if the model uses oil that is five times more viscous than water, with SGo = 0.8 by using Reynolds number law.

In the second experiment a beam is simply supported at its two ends then loaded in the middle as seen in Figure 2 below. A dial gauge is used to measure the deflection at the middle, while a gauge on each end is used to measure the inclination of the beam at the supports (to compare to theoretical values).
