If this is a classroom lab experiment you might consider a 1" strip. A cantilever sensor can be operated in two different modes: the static mode, where the cantilever deflection is monitored, and the dynamic mode, where the cantilever resonance is monitored.

The deflection of a cantilever can be due to number of processes such as molecular adsorption, thermal effects, electric and magnetic fields, and fluid by: According to the mechanics analysis of the flexible cantilever beam in the uniform Experimental deflection survey of cantilever sectors of uniform thickness book distribution, the corresponding mathematical model is established.

The first 2/3rd portion of the cantilever beam is L shaped and in the last 1/3 portion, the beam flatens out into a regular rectangle cross section. I broke the beam into 2 pieces and got the deflection and stress in the L shaped portion but I am not sure how to go about the last 1/3rd portion where the beam is continiously.

Bending moments are produced by transverse loads applied to beams. The simplest case is the cantilever beam, widely encountered in balconies, aircraft wings, diving boards bending moment acting on a section of the beam, due to an applied transverse force, is given by the product of the applied force and its distance from that section.

It thus has units of N m. Over-deflection of beam in continuous rigid frame bridge has become an serious problem in recent years. The reason is complex. Some reseachers think that the bad quality of sectional joints in cantilever construction will cause additional shearing deformation and affect the beam deflection, this idea need to be further studied.
