Consider the pendulum shown above. A spherical mass M = 14.0 kg
attached to a string starts at rest with the string horizontal as
shown in the top diagram.
The mass is released and swings down as shown in the bottom
diagram. However, the string will break if the tension is equal or
greater than 160 N.
At what angle ?, as shown in the diagram, will the string
break?

Consider the scenario shown in the diagram below. A box (mass m1) is on a slope, which is inclined at an angle theta with respect to the horizontal. The box is connected via a string and pulley to a hanging weight (mass m2). The string and the pulley are assumed to be massless and frictionless, but there is friction between the box and the incline (with coefficient of kinetic friction mu k). Find an expression for the tension T in...

Consider the two dimensional Control Volume (CV) shown below in Fig. 1.1 for the special case of steady-state flow with v = 0 and a uniform pressure gradient vp = dp/axi = Ci everywhere C is a non-zero constant. These assumptions mean that both viscous shear stresses t = and compressive stresses due to pressure act on the fluid in the CV. You can also assume that there is no momentum source. - at itayº ..

Pulling Two Blocks
In the situation shown in the figure, a person is pulling with a
constant, nonzero force F⃗ on string 1, which is attached
to block A. Block A is also attached to block B via string 2, as
shown.
For this problem, assume that neither string stretches and that
friction is negligible. Both blocks have finite (nonzero) mass.

An object of mass M is used to provide tension in a 4.5-m-long string that has a mass of 0.272 kg, as shown in the figure below. A standing wave that has a wavelength equal to 1.5 m is produced by a source that vibrates at 30 Hz. 1) Calculate the value of M. (Express your answer to two significant figures.)
