A revolving door is made of four rectangular sections.?
The mass of each section is 78 kg. A person who carries on the outer edge a section with a force of F = 69 N that is perpendicular to the section. To determine the magnitude of the angular acceleration the door.
I = ^ 2 mW / 3 (where W is the width) = 4 * 78 * W ^ 2 ^ T = 2.3 Nms pair FW = 69W Nm alpha = T / I = 69 * 3 / (4 * 78 * W ) ^ Rad / s 2, you need to know to get a W numerical answer. However, you can find the acceleration of translation from the edge the door. W * a = alpha = 69 * 3 / (4 * 78) = 0.663462 ^ m / s 2
