Conical Pendulum
A mass attached at the end of a massless string swings around in a horizontal circle (the string sweeps out a cone). Let θ be the angle the string makes with the vertical, l be the length of the string, h is the vertical height of the string, and r is the radius of the circle. So, l is the hypotenuse of a right triangle with h and r as legs, and θ as the upper angle. The length of the string l is slowly increased (or decreased). (a) Assuming that θ is very small, how does r depend on l? (b) Assuming that θ is very close to π/2, how does h depend on l? Use newtonian mechanics and angular momentum to solve

3. CONICAL PENDULUM A conical pendulum is a piece of physics apparatus in which a massive bob, connected to a string (which also connects to the ceiling) swings around in a horizontal circle. The string traces out the surface of a cone, thus the name conical pendulum. See: Ihttps://www.youtube.com/watch?v 3Tf9xXsgqD4. The bob has mass m, the string length is L and the circle has radius R. Find expressions for the following in terms of the given quantities, and g a)...

A conical pendulum consists of a mass hanging from a string while moving in a horizontal circle of radius r (see Figure 1; the blue arrow indicating velocity is pointing “into” the page, not up.). If the mass moves at constant speed 1.3 m/s and the angle the string does with the vertical is θ = 12◦ , what is the radius r of the circle? (Hint: This is similar to the “hanging chairs” problem from class.)

Consider a conical pendulum with a bob of mass m = 78.0 kg on a string of length L = 10.0 m that makes an angle of θ = 7.00° with the vertical. (Consider +î to be towards the center of the circular path and +ĵ to be upward.) (a) Determine the horizontal and vertical components of the force exerted by the string on the pendulum. (b) Determine the radial acceleration of the bob.

A bob of mass m is suspended from a fixed point with a massless string of length L (i.e., it is a pendulum). You are to investigate the motion in which the string moves in a cone with half-angle θ. 1. What tangential speed, v, must the bob have so that it moves in a horizontal circle with the string always making an angle θ from the vertical? Express your answer in terms of some or all of the variables...

The figure below shows a "conical pendulum", in which the bob
(the small object at the lower end of the cord) moves in a
horizontal circle at constant speed. (The cord sweeps out a cone as
the bob rotates.) The bob has a mass of 0.050 kg, the string has
length L = 0.66 m and negligible mass, and the bob follows a
circular path of circumference 0.86 m.
