Physical pendulums with SHM. Compare period of ring to that of bar.

A thin uniform ring, placed on a knife edge pivot executes SHM period 'Tr'. The same ring is cut, then straightened to form a bar, which executes SHM with a period 'Tb'. Find the ratio of periods, Tb/Tr.

A page of extremely useful formulas for mechanics.

Equations include those for linear motion, rotary motion, momentum, energy, etc. This is a great study tool, if a student is capable of understanding and using these formulas they should be able to do well on any exam in this area.

finding the final velocity of a falling object

A construction worker on a new high-rise building drops a wrench and it falls 78.4 m to the ground. How fast is it moving when it hits, assuming no air resistance? Use g = 9.8 m/s2.

Object of mass 2M moving with SHM. Describe effects: A. If one mass detaches at xm, B. If one mass detaches at center.

Driven by a spring with force constant k, on a horizontal frictionless table, two joined masses, each mass M, is executing SHM between xm and -xm. Known parameter values are: M= 2 kg, k= 64 nt/m, xm= .25 m, SEE ATTACHMENT #1 for diagram showing parameters, and general equations of SHM. PART a. Find the period, and maximum ...continues

Find the maximum height of a cannonball fired at an angle from the ground.

A battalion of soldiers aims their cannon at an angle of 30° up from horizontal and fires it as shown below in a large, level field. The initial speed of the cannon ball is 196 m/s. Neglect air resistance and assume that the cannon ball starts at ground level for simplicity. Use g = 9.8 m/s2. What is the maximum height reac ...continues

Two springs with different force constants have one end fixed. Their free ends are pulled together to connect.

In a box with vertical sides, two springs have one end fixed on opposite sides of the box. The free ends are distance S= .64 meters apart. SEE ATTACHMENT #1 for a diagram of initial and final conditions. When the free ends are pulled together and joined, find the change in the length of each spring. Their force constants are: ...continues

A rectangle made of two uniform bars lengths L, mass A, and two of length W, mass B, oscillates with SHM about an axis at one corner.

A rectangular frame is made from two thin, uniform bars of length L= 4 m, mass A= 6 kg, and two of length W= 3 m, mass B= 1.5 kg. The frame is placed on a pivot axis at one corner and executes SHM about that axis. Find the period of this SHM oscillation. SEE ATTACHMENT #1 for a diagram of the given parameters.

Traveling waves represented as a sine curve, with general information and basic equation.

Some parameters which all traveling waves have include its wavelength (lambda), period T, wave speed v, amplitude ym, etc. ATTACHMENT #1 is a diagram of a typical wave, a sine curve, with points A, B, etc. identifying various points and lengths of a wave. PART a. On ATTACHMENT #1, in the spaces shown after the parameters listed ...continues
