Question

For the following cantilever beam with rectangular cross-section, discuss whether a horizontal or vertical transverse load on the end of the beam will give a greater magnitude of the end deflection and why? The circle has a diameter of 10 mm

Answer 1

Answer:

correct answer is Both is same magnitude

Explanation:

given data

circle diameter = 10 mm

to find out

magnitude of the end deflection

solution

we know end deflection of cantilever is express as

end deflection of cantilever = $\frac{PL^3}{3EI}$    ......................1

so

moment of Inertia about any axis will be same for circular cross section

so that here Both will have same magnitude  with diameter 10 mm

so correct answer is Both is same magnitude
