Mechanical energy is the sum of kinetic energy and potential energy in an object that is used to do a particular work. In other words, it describes the energy of an object because of its motion or position, or both. Let us consider the example of an ideal simple pendulum (friction-less). We can see that the mechanical energy of this system is a ...
Statistical Mechanics. This branch of statistical mechanics which treats and extends classical thermodynamics is known as statistical thermodynamics or equilibrium statistical mechanics. We apply statistical mechanics to solve real systems (a system for many particles). We can easily solve Schrodinger’s equation for 1 particle, atom or molecule.
Mechanical waves are waves that need a medium for propagation. Non-mechanical waves are waves that do not need any medium for propagation. Sound waves, water waves and seismic waves are some examples of mechanical waves. The electromagnetic wave is the only non-mechanical wave. Mechanical waves cannot travel through vacuum.
MA is the mechanical advantage, F B = force of the object and. F A = effort to overcome the force of the object. Example 1. Estimate the mechanical advantage if 400 N force is needed to overcome the load of 900 N. Solution: F A = 400 N. F B = 900 N. The formula of mechanical advantage is. MA = F B / F A. MA = 9 00 / 400. MA = 2.25
Hooke’s Law states that the strain of the material is proportional to the applied stress within the elastic limit of that material. Mathematically, Hooke’s law is commonly expressed as: F = –k.x. Where F is the force, x is the extension in length, and k is the constant of proportionality known as the spring constant in N/m. Read More ...
Find the power delivered to the truck. [Given: 1000 kg as the mass of the truck] First we need to calculate the work done, which requires the force necessary to lift the truck against gravity: F = mg = 1000 x 9.81 = 9810 N. W = Fd = 9810N x 2m = 19620 Nm = 19620 J. The power is P = W/t = 19620J / 15s = 1308 J/s = 1308 W.
Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever. Machine components designed to manage ...
Torque is the measure of the force that can cause an object to rotate about an axis. Force is what causes an object to accelerate in linear kinematics. Similarly, torque is what causes an angular acceleration. Hence, torque can be defined as the rotational equivalent of linear force. The straight line about which the object rotates is called ...
Resonance is witnessed in objects in equilibrium with acting forces and could keep vibrating for a long time under perfect conditions. To find the resonant frequency of a single continuous wave, we use the formula, \ (\begin {array} {l}v = λf\end {array} \) Where v is the wave velocity and λ is the distance of the wavelength.
Waves in which the medium moves at right angles to the direction of the wave. Examples of transverse waves: Water waves (ripples of gravity waves, not sound through water) Light waves. S-wave earthquake waves. Stringed instruments. Torsion wave. The high point of a transverse wave is a crest. The low part is a trough.
