Tapered beams are used in a variety of applications to save both weight and cost. Indeed, we see them in bridges, churches and tree branches. Despite their weight savings, the weight of the beam must be consider when designing the structure lest it will fail. Consider the illustrated tapered wood beam of length l = 7 m, thickness (into the screen) t = 10 cm, and big and small end heights hbig = 80 cm and hsmall = 40 cm. Knowing that the mass density of wood is p= 800 kg/m³, determine the resultant force FR in N and resultant moment MR in Nm about the base, i.e. big end, due to the weight of the beam. MATLAB input variables: format shortEng 1 = 7;%m t = 10/100;%m h_{big} = 80/100;%m h_{small} = 40/100;%m rho = 800; g=9.81;%m/s^2 FR= N MR = |)N m

Consider the same cantilevered thin-walled I-beam with web and flange thickness 1 mm, height 14 cm, and width 9 cm. The beam is made of a material with a yield stress of 250 MPa. If the only load on this beam is a tip moment, what is the maximum bending moment (in Nm) the beam cross-section can carry (it will lead to yield and plasticity in the entire cross section of the beam)? Assume the beam material is elastic - perfectly plastic.
