For a 6 m long horizontal cantilever beam PQR, Q is the mid-point. Segment PQ of the beam has a flexural rigidity EI = 2 × 105 kN·m2, whereas segment QR has infinite flexural rigidity. Segment QR is subjected to a uniformly distributed, vertically downward load of 5 kN/m. The magnitude of the vertical displacement (in mm) at point Q is:

Which type of retaining wall relies on its own weight for stability, resulting in a large and massive structure?

Which of the following structural elements is NOT a compression member?

A retaining wall consisting of a thin vertical stem and a thin base slab, reinforced with thin vertical transverse ribs at regular intervals on the back face to reduce bending moments, is known as a:
