Small blocks, each with mass m, are clamped at the ends and at the center of a rod of length l and negligible mass. compute the moment of inertia of the system about an axis perpendicular to the rod and passing through (a) the center of the rod and (b) a point one-fourth of the length from one end

Answered

Explanation:

a) Two balls are at a distance of L/2 from the axis of rotation and one block at the center. ( center of rod).

therefore,

b) two balls at a distance L/4 at the from the axis and 1 ball at a distance 3L/4 from the from the axis.

=

a) cold, dry

explanation:

continental polar masses are cold and dry air masses because the cold air cannot hold much moisture. as they move into warmer air, they can trigger precipitation.

not too sure thinking all accelerations are pointed down
