A solid cylinder, a thin hollow cylinder (with circular
cross-section), and a thick hollow cylinder (with a donut cross
section), of equal masses radii, are simultaneously released from
rest at the top of an inclined plane and roll without slipping down
the plane. Which object reaches the bottom of the inclined plane
first?
A) The solid cylinder
B) The thin hollow cylinder
C) The thick hollow cylinder
D) All objects reach the bottom at the same time
Please provide explanation.

A hollow sphere, a solid cylinder, and a hollow cylinder are all
released from rest at the top of a ramp. Which object reaches the
bottom of the ramp first?
(a) The hollow sphere (b) The solid cylinder
(c) The hollow cylinder
(d) They all reach the bottom of the ramp at the same time
A hollow sphere, a solid cylinder, and a hollow cylinder are all
released from rest at the top of a ramp. Which object has the...
Rotational Inertia –Rolling Kinetic Energy.
A solid sphere, a hollow sphere, a hollow cylinder, and a solid
cylinder, all of with same mass (M=0.25 kg ) and radius(R= 0.20 m)
– are placed at the top of an incline at height (h= 1.5 m ). All
the objects are released from rest at the same moment to roll down
without slipping.
Hint: search for the rotational inertia formula for each of the
rolling object first. Then calculate each of them...
A solid sphere of radius R, a solid cylinder of radius R, and a
hollow cylinder of radius R all have the same mass, and all three
are rotating with the same angular velocity. The sphere is rotating
around an axis through its center, and each cylinder is rotating
around its symmetry axis. Which one has the greatest rotational
kinetic energy?
both cylinders have the same rotational kinetic energy
the solid cylinder
the solid sphere
they all have the same...
1. What is a masonry solid unit? And a
hollow unit?
2. Facing bricks may be classified as FBS
(standard), FBX (extra special), and FBA (architectural). What is
the basis for this classification?
3. A CMU scored unite may be used to
simulate a stack-bond wall, when the wall is in fact, made with a
running-bond pattern. What is the advantage of having a
running-bond pattern when compared to a stack-bond pattern?

A solid and hollow shaft, connected by a coupling, transmit
power. The outside diameters of the shafts are the same and the
inside diameter of the hollow shaft is 75% of its outside diameter.
The solid shaft is three times as long as the hollow shaft. Take
the modulus of rigidity for both shafts as 80 GPa. (a) If the angle
of twist for the solid shaft is 1 degree, find the angle of twist
for the hollow shaft. (b)...
