The deflection profile y (x) of a cantilever beam due to application of a point force F (in Newton), as a function of distance x from its base, is given by y(x) = 0.001F x2(1 - x/3)m. The angular deformation θ at the end of the cantilever is measured by reflecting a laser beam off a mirror M as shown in the figure.
The translation S of the spot of laser light on the photo detector when a force of F = 1 N is applied to the cantilever is -
