2. Consider a cantilevered beam with length L = 3 m, uniform E = 180 GPa, Iz- 5.375 × 10-8 m. and ρ 3.0 kg/m. (a) (20 points) Compute, by hand, the first 5 (lowest) natural frequencies for this beam. Note, unlike for the simply-supported beam problem, you will not be able to solve, analytically, the transcendental equation obtained from the application of the boundary conditions to the general free vibration solution. So, use Matlab roots of this equation numerically

Question 4 A uniform beam of arbitrary, unsymmetrical cross-section and length 21 is built-in at one end and simply supported in the vertical direction at a point half-way along its length. This support, however, allows the beam to deflect freely in the horizontal x direction (Figure Q4) For a vertical load W applied at the free end of the beam, calculate and draw the bending moment diagram, putting in the principal values. Figure Q4 [Answers: M.-0, MB-WI, MA--W1/2 linear distribution...

1. Consider a beam of length L that is hinged at one end and supported by a cord at the other as shown in the figure. Suppose a mass M is hung at a distance of d from the hinge and that the supporting cord makes an angle of q 30 with the horizontal. Attached to the other end of the cord is a mass m. Take the mass of the beam m, to be equal...

Problem 1 A cantilever beam of length L is clamped at its left end (x = 0) and is free at its right end (x = L). Along with the fourth-order differential equation EIy(4) = w(x), it satisfies the given boundary conditions y(0) = y′(0) = 0,y′′(L) = y′′′(L) = 0. a) If the load w(x) = w0 a constant, is distributed uniformly, determine the deflection y(x). b) Graph the deflection curve when w0 = 24EI and L = 1....
