A beam with one end fixed and the other simply supported is known as propped cantilever. Which of the above statements is/are correct ? Correct Answer 1 and 4 only

Explanation:

The different types of beam are:

Cantilever beam: 

A beam fixed at one end and free at the other end is known as a cantilever beam.

Simply Supported beam:

A beam supported at its both ends by rollers is known as a simply supported beam.

Fixed beam: 

A beam whose both ends are fixed is known as a fixed beam.

Continuous beam: 

A beam supported on more than two supports is known as a continuous beam.

Overhanging beam: 

A beam having its end portion extended beyond the support, is known as overhanging beam. A beam may be overhanging on one side or on both sides.

Propped cantilever beam:

The propped cantilever beam is a beam with one end fixed and the other end simply supported.

It comes under statically indeterminate beams.

Two beams PQ (fixed at P and with a roller support at Q, as shown in Figure I, which allows vertical movement) and XZ (with a hinge at Y) are shown in the Figures I and II respectively. The spans of PQ and XZ are L and 2L respectively.
