Question. 3 A circular disc mounted on a shaft carries three attached masses of 4 kg, 3 kg and 2.5 kg at radial distances of 75 mm, 85 mm and 50 mm and at the angular positions of 45°, 135° and 240° respectively. The angular positions are measured counterclockwise from the reference line along the x-axis. Determine the amount of the counter mass at a radial distance of 75 mm required for the static balance.

Step 1

Static balance means that the vector sum of all mass-radius products (centrifugal forces) is zero. Let's denote the masses as $m_1, m_2, m_3$ and their respective radial distances as $r_1, r_2, r_3$ and angular positions as $\theta_1, \theta_2, Show more…
