Problem 13.39. The sphere al A is given a downward velocity v, of magnitude 5 m/s and swings in a vertical plane at the end of a rope of length / 2 m attached to a support at O. Determine the angle at which the rope will break, knowing that it can withstand a maximum tension equal to twice the weight of the sphere. b.) using the equations Shown how do...
A mass m = 5 kg is tied on one end of a rope and is forced to execute a circle on a vertical plane so that in completes one revolution every second. If the maximum tension that the rope can withstand is 1000 N, find the maximum length that the rope can have without breaking. Use g = 10 m/s2.
Exercise of conservation theorems:
the sphere of mass m of the simple pendulum of the figure is
released from rest when the string makes an angle β1 with the
vertical; Based on this information:
Determine one expression for velocity and another for tension at
the lowest point ②.
A pendulum of 61.0 m in length and 0.400 kg of mass is released
from rest when the rope is at an angle of 65.0 or vertical. Find

A 2 kg bag is gently pushed off the top of a wall at A and swings in a vertical plane at the end of a 1m- long rope Determine the velocity (m/s) of the bag when 0=30°. The rope applies a tension equal to thrice the weight of the bag a В
To understand the concept of tension and the relationship
between tension and force. This problem introduces the concept of
tension. The example is a rope, oriented vertically, that is being
pulled from both ends. (Figure 1) Let Fu and Fd (with u for up and
d for down) represent the magnitude of the forces acting on the top
and bottom of the rope, respectively. Assume that the rope is
massless, so that its weight is negligible compared with the
tension....

A m = 2.45 kg object hangs in equilibrium at the end of a rope (taken as massless) while a wind pushes the object with a F W = 15.7 N horizontal force. Find the magnitude of the tension in the rope and the rope's angle from the vertical. The acceleration due to gravity is g = 9.81 m/s2. A ball attached to the end of a rope hangs from an overhead support. The rope is straight, and hangs at...
7. A fluid flows past a sphere with an upstream velocity of Vo = 40 m/s as shown in the figure below. From a more advanced theory, it is found that the speed of the fluid along the front part of the sphere is V = (3/2)Vo sin 0. 40° VO, - r oka (a) Determine the streamwise and normal components of the acceleration at point A if the radius of the sphere is a = 0.20 m.
