Certainly, if you assume the arm is uniform and the bob is small enough to treat as a point (or has a calculable MI).HalcyonicBlues said:can the mass of the arm be calculated (or at least estimated) if the period, length of the arm and mass of the bob are known?
The mass of a physical pendulum can be calculated by using the equation M = (T^2 * L) / (4π^2 * g), where M is the mass of the pendulum, T is the period of oscillation, L is the length of the pendulum, and g is the acceleration due to gravity.
Yes, the mass of the physical pendulum does affect its period of oscillation. The larger the mass, the longer the period of oscillation will be.
Yes, the mass of the physical pendulum can be calculated using only the length and period of oscillation, as long as the acceleration due to gravity is known.
The length of the physical pendulum has a direct effect on its period of oscillation. The longer the length, the longer the period of oscillation will be.
The relationship between the mass and length of a physical pendulum is not a direct one. The mass and length both affect the period of oscillation, but in different ways. Increasing the mass will increase the period, while increasing the length will decrease the period.
