試題 :
1.The cylinder show in the figure is held in position by a rope that supplies
for a force F and by static friction. What is the minimum value of μs such
that the cylinder will remain in equilibrium when F is at the angle θ
with the horizontal?
2.A vehicle, mass m, is propelled in a straight horizontal line by an engine
delivering a constant power P. If the vehicle starts from rest, how long does
it travel in a time t?
3.Four bricks of length L, identical and uniform, are stacked on top of one
another in such way that part of each extends beyond the one beneath. Find,
in terms of L, the maximum values of (a)a1,(b)a2,(c)a3,(d)a4,(e)h, such that
the stack is in equilibrium.
4.Calculate the rotational inertia of an annular cylinder of mass M with inner
radius R1 and outer radius R2.
5.Suppose a solid disk of radius R is given an angular velocity ω0 and
about an axis through its center and is then lowered to a rough, horizontal
surface and released. Assume that the coefficient of the friction between
the disk and the surface is μ.
(a)How much time does it take for pure rolling motion to occur?
(b)What is the distance the disk travels before pure rolling occurs?
