How to Calculate Dynamic Force - The Classroom

Its initial velocity would be 0 because it wasn't moving until you threw it. Subtract 0 from your Step 2 number. Divide that by the time you measured with your stopwatch in Step 2. This is acceleration. Multiply the mass of your object (from Step 1) by the acceleration of your object (from Step 3). The number you get is the dynamic force of ...

Vibrations of Cantilever Beams: - University of Nebraska-Lincoln

When the force, P, is removed from a displaced beam, the beam will return to its original shape. However, inertia of the beam will cause the beam to vibrate around that initial location. Assuming the elastic modulus, inertia, and cross sectional area (A) are constant along the beam length, the equation for that vibration is (Volterra, p. 310)

For vibration, the distances are very small, so we typically use microns (1/1000 mm) or mils (1/1000 inch). Velocity is the Time rate of change of displacement. For transportation, we use large units such as km/hr or miles/hr. For vibration, It is measured in mm/s or IPS. Acceleration is the Time rate of change of velocity.
