SI units problem 20

A beam is clamped at one end and an object X is attached to the other end of the beam, as shown in the figure below.

The object X is made to oscillate vertically. The time period of the oscillations is given by


is the mass of X,

is the length between the clamp and X,

is the Young modulus of the material of the beam, and

is a constant.

  • Show that the SΙ base units of the Young modulus are .

  • Determine the SΙ base units of .
