A body tied to a string of length l

The frequency of oscillation of a string stretched under tension T is given by. Get Started.

The string is just taut when the body is at the highest point. The velocity of the second body after the collision is. The further distance it travels before coming to rest is. A body is moving in a vertical circle of radius r such that the string is just taut at its highest point. The speed of the particle when the string is horizontal is.

Derive the expression for the velocity of the body and the tension in the string at any point; hence find the tension at the bottom and top of the circle. Also, calculate the minimum velocity at the lowest point so that it is just able to loop the loop and calculate the minimum velocity at the top. A body attached to a string of length describes a vertical circle such that it is just able to cross the highest point. Find the minimum velocity at the bottom of the circle. Find the tension in the string. Vertical circular motion

The force diagrams for the system consisting of the rope and block is shown in Figure 8. The forces on the rope and the block must each sum to zero. If we consider the case that the rope is very light, then the forces acting at the ends of the rope are nearly horizontal. Thus the applied pulling force is transmitted through the rope to the block since it has the same magnitude as the force of the rope on the block. In addition, the applied pulling force is also equal to the friction force on the block. The imaginary slice divides the rope into two sections, labeled L left and R right , as shown in Figure 8. There is now a Third Law pair of forces acting between the left and right sections of the rope. The force diagram for the left and right sections are shown in Figure 8. For a rope of negligible mass, under tension, as in the above case, even if the rope is accelerating the sum of the horizontal forces applied to the left section and the right section of the rope are zero, and therefore the tension is uniform and is equal to the applied pulling force,. Determine the tension in the rope as a function of distance x from the block.

Pendulums are in common usage. Grandfather clocks use a pendulum to keep time and a pendulum can be used to measure the acceleration due to gravity. For small displacements, a pendulum is a simple harmonic oscillator. Here, the only forces acting on the bob are the force of gravity i. The mass of the string is assumed to be negligible as compared to the mass of the bob. Consider the torque on the pendulum. The force providing the restoring torque is the component of the weight of the pendulum bob that acts along the arc length. The torque is the length of the string L times the component of the net force that is perpendicular to the radius of the arc. The minus sign indicates the torque acts in the opposite direction of the angular displacement:. The solution to this differential equation involves advanced calculus, and is beyond the scope of this text.
