WebNewton’s Second Law for Rotation. If more than one torque acts on a rigid body about a fixed axis, then the sum of the torques equals the moment of inertia times the angular acceleration: ∑ i τ i = I α. 10.25. The term I α is a scalar quantity and can be positive or negative (counterclockwise or clockwise) depending upon the sign of the ... WebFor the spring-mass system in the preceding section, we know that the mass can only move in one direction, and so specifying the length of the spring s will completely …

WebA 200 g block on a 50-c m-long string swings in a circle on a horizontal, frictionless table at 75 r p m. Step 2: Explanation (Part a) The block velocity is tangent to the circle of … WebThe left end of the rod is attached to a vertical support by a frictionless hinge that allows the rod to swing up or down. The right end of the rod is supported by a cord that makes an angle of 30 with the rod. A spring scale of negligible mass measures the tension in the cord. A 0.50 kg block is also attached to the right end of the rod. WebThe orange vector is the component of this velocity which is perpendicular to the rod, v cos ( θ). From the bottom point of the rod, the linear velocity a distance l / 2 away is v cos ( θ), so the angular velocity d θ d t = ω = 2 v cos ( θ) l. Using this result, we can find the rotational kinetic energy to be E r = 1 2 m l 2 12 ( 2 v cos ... cbs strategy
