A body of mass m is suspended by a rod of length L that pivots without friction (as shown). The mass is slowly lifted along a circular arc to a height h.
a. Assuming the only force acting on the mass is the gravitational force, show that the component of this force acting along the arc of motion is F = mg sin u.
b. Noting that an element of length along the path of the pendulum is ds = L du, evaluate an integral in u to show that the work done in lifting the mass to a height h is mgh.
If you substitute the expressions for ω1 and ω2 into Equation 9.1 and use the trigonometric identities cos(a+b) = cos(a)cos(b) - sin(a)sin(b) and cos(a-b) = cos(a)cos(b) + sin(a)sin(b), you can derive Equation 9.4.
How does equation 9.4 differ from the equation of a simple harmonic oscillator? (see attached image)
Group of answer choices
A. The amplitude, Amod, is twice the amplitude of the simple harmonic oscillator, A.
B. The amplitude is time dependent
C. The oscillatory behavior is a function of the amplitude, A instead of the period, T.
D. It does not differ from a simple harmonic oscillator.
Question 2
a) A laminar boundary layer profile may be assumed to be approximately of the form
u/Ue= f (n)=f(y/8)
i) Use an integral analysis with the following two-segment velocity profile,
ƒ (n)=(n/6)(10–3n−1³), for 0≤7≤0.293 and ƒ (7) = sin (л7/2) for 0.293≤n≤1,
to find expressions for the displacement thickness &*, the momentum thickness e,
the shape factor H, the skin-friction coefficient c, and the drag coefficient CD.
ii) Derive an expression for the velocity normal to the stream wise direction given that,
u/U₂ = f(n).
iii) Hence obtain the velocity normal to the stream wise direction for the above two-
segment velocity profile.
