1
Q
Define tensile and compressive forces-
A
– When two forces stretch a body, they are described as tensile
–When two forces compress a body, they are known as compressive
2
Q
Define Hooke’s law-
A
provided elastic limit is not exceeded, the extension of an object is proportional to the applied force (load).
3
Q
Write linear relationship is represented by the Hooke’s law equation:
A
F = kx
force= spring constant x extension
N = Nm-1 x m
The constant of proportionality is spring constant k. also can be calculated by finding the gradient of the linear part of Force and extension graph
