Question 2.
A smooth uniform sphere of mass m and radius r is squeezed between two massless levers, each of
length 1, which are inclined at an angle with the vertical. A mechanism at pivot point O ensures
that the angles & remain the same at all times so that the sphere moves straight upward. This
problem is based on Problem 3-1 in the text.

a) Draw appropriate freebody diagrams of the system assuming that there is no friction.
b) Draw appropriate freebody diagrams of the system assuming that there is a coefficient of
friction between the sphere and the right lever of μ.
c) If a force P is applied between the ends of the levers (shown in the diagram), and there is no
friction, what is the acceleration of the sphere when = 30°
If you had a matrix A = [1 2 3; 4 5 6; 7 8 9] and a matrix B = [1 2 3], how would you cross multiply them i.e. what is the cross product of AxB. what would be the cross product of a dyadic with a vector?
Problem 3: The inertia matrix can be written in dyadic form which is particularly useful
when inertia information is required in various vector bases. On the next page is a right
rectangular pyramid of total mass m. Note the location of point Q.
(a) Determine the inertia dyadic for the pyramid P, relative to point Q, i.e., 7%, for unit
vectors ₁₁, 2, 3.
