Question 1

what is A beam

Answer 1

horizontal structural member used to support loads. Beams are used to
support the roof and floors in buildings. Beams are structural members which offer resistance to bending due to applied loads.

are long prismatic bars, and the loads are usually applied normal to the
axes of the bars.

Question 2

statically determinate beams.

Answer 2

Beams supported so that their external support reactions can be calculated by the methods of statics alone

Question 3

statically
indeterminate.

Answer 3

A beam which has more supports than needed to provide equilibrium

To determine the support reactions we must consider its load-
deformation properties in addition to the equations of static equilibrium.
