Question
a) Let R represent the reaction force at Support B. By releasing the beam at Support B and imposing a force R at Point B, the deflection of the beam consists of two parts,i.e.
Part I- the deflection caused by MB ;
Part II- the deflection caused by R
Please treat R, w, h , L , E as variables in this step , the mathematical equation for the deflection at Point B caused by R ( Part II) can be written as
(Hint : to input equation R2LQ2wh , you can type (R^2*L)/(Q^2*w*h) )
b) Using the provided data:
- cross-section width w = 20 mm,
- cross-section hight h = 93 mm,
- length of the beam L =3 m ,
- beam material’s Young’s modulus Q =226 GPa,
- applied bending moment MB = 11 kN.m
The value of the deflection at Point B caused by MB ( Part I) can be calculated as ......(in mm)
