Finding the max. deflection of the beam

[farry1024]

For the Electronic Bathroom Scale. The maximum load on a
beam is assumed to be 75kg.

(a) Find the max. deflection by using the Young’s Modulus
E=200,000 N/mm². Is it small? Also see next page for the
dimensions of the beam. Hint: For small deflection, tan phyter » phyter.
Use the given Excel template file if needs.

(b) Determine the relationship of the applied load (say, mass in kg
here!) against the beam surface strain (e). Hint: Using Excel to
calculate the Bending Moment at the surfaces of the beam first.
Then use the equation (M/I)(h/2) = Ee.

(c) What have you observed?

What formula should I use the find the max. deflection?
