A simply supported beam with a span of 8 m is subjected to a point load of 10 kN at midspan. What is the maximum bending moment in the beam?

The maximum bending moment in a simply supported beam occurs at midspan and is calculated as M = (w x L) / 4, where w is the point load and L is the span. In this case, M = (10 kN x 8 m) / 4 = 40 kNm.

What is the recommended minimum stopping sight distance (SSD) for a highway with a design speed of 60 km/h?

According to the AASHTO Green Book, the minimum SSD for a highway with a design speed of 60 km/h is approximately 100 m, considering a perception-reaction time of 2.5 seconds and a deceleration rate of 3.5 m/s^2.

A soil sample has a liquid limit of 40% and a plastic limit of 20%. What is its plasticity index?

The plasticity index (PI) is calculated as PI = LL - PL, where LL is the liquid limit and PL is the plastic limit. In this case, PI = 40 - 20 = 20.
