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.

A80 A compressed spring is used to propel a ball-
bearing along a track which contains a circular
loop of radius 0.10m in a vertical planc. The
spring obeys Hooke's law and requires a force
of 0.20 N to compres it 1.0 mm.
0.10 m
(a) The spring is compresied by 30 mm.
Culculate the energy stored in the spring.
(b) A tal-bearing of mass 0.025 kg is placed
against the end of the spring which is then
released. Calculete
(i) the speed with which the ball-
bearing leaves the spring,
(ii) the speed of the bail at the top of the
locp,
(iii) the force exerted on the ball by the
track at the top of the loop.
Assume that the effects of friction can be
ignored.
