Concept explainers

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Question

Show all working explaining detailly each step.

A93 (a) Explain what is meant by moment of inertia
and angular momentum. State the relation-
ship between them.
(b) Explain the following obscrvations:
(1) Flywhcels are eften large diameter
wheels with heavy rims rather than
disc type wheels of constant thick-
ness.
(ii) A pirouerting skater rotates faster as
she draws her arms closer to her
body.
(c) In a single cyiinder petrol engine, energy
from the combustion process is supplied
to the crankshaft (the axle of the engine)
once every two rotations of the crankshaft,
namely during each power stroke , and a
flywheel is attached to the crankshaft to
smooth the motion.
In such an engine each power stroke
produces mechanical energy E= 1 kj,
and its flywheel has moment of inertia
I = 0.5 kg m.
