Gears - Gears are like a continuously rotating lever. By using different sizes of wheels, and different numbers of teeth, you can use gears as force multipliers or as distance multipliers. Figure above shows two cogs one with twice as many teeth as the other. The cog teeth fit t..

In these type of levers the load is situated between fulcrum and effort.(shown in the figure belo..

The numerical value of equilibrium constant depends upon the stoichiometry of the chemical equation used in representing the reaction. For example, the reaction can also be expressed as Then, the corresponding equilibrium constants are When the coefficients are doubled, then the K for th..

x 2 - 2x - 48 = x 2 - 8x + 6x - 48 = x(x - 8) + 6(x - 8) = (x - 8) (x + 6) When the coefficient of the highest power is not unity. i.e., type ax 2 bx c, when and b and c are integers. Multiply (3x + 2) (x + 4) and consider the result so obtained. = 3x (x + 4) +2 (..

Linear Equations in One Variable - An equation of one variable and of first order (i.e., its highest power is one) is called a Linear equation. Such an equation has only one solution. A solution is also called the 'root' of the given equation.An equation of one variable and of first order..
