Calculation that takes into account the concentration of a chemical and the time of exposure in order to determine the average exposure level over a given timeframe.

The lowest concentration of a flammable vapor in air that will support combustion in the presence of an ignition source. It's the point below which the mixture will not ignite.

A measure of the concentration of a substance in air that represents the level below which most workers can be repeatedly exposed without adverse effects, as determined by regulations.

The combined gas law equation combines Boyle's law and Charles' law. It describes the relationship between pressure, volume, and temperature of a gas. This law can be used to predict how gases behave under changing conditions.

This formula shows how the total resistance when resistors are connected in series is calculated. The total resistance is the sum of individual resistances.

This equation demonstrates how the total power in a circuit is calculated. Power is the rate at which energy is consumed or transferred.

This equation shows how the total resistance is calculated when resistors are connected in parallel. Each resistor provides an alternate path for the current, reducing overall resistance.

This fundamental law of electrical circuits relates voltage (V), current (I), and resistance (R). It states that the voltage across a conductor is directly proportional to the current flowing through it, and the constant of proportionality is the resistance.

The probability of an event occurring in a specific timeframe (e.g., the probability of a machine failing within a year).

The rate at which an event is expected to occur, usually calculated as the average number of events per unit of time.

A statistical measure that indicates how closely data points are clustered around the mean. A Z-score of 0 represents the mean. Values greater than 0 are above the mean, and values less than 0 are below the mean.

A statistical measure that describes the variability or spread of a set of data. It indicates how far, on average, data points are from the mean.

The calculated value that represents the strength and direction of a linear relationship between two variables. Values range from -1 to 1 where a value of 1 indicates a positive linear relationship and -1 indicates a negative relationship.

Measure of the capacity of a fluid flowing through a pipe which is measured in gallons per minute (gpm).

Measure of force per unit area, usually expressed in pounds per square inch (psi).

A measure of the roughness of a pipe's interior surface. Influences the pressure drop and flow rate through the pipe.

A measure of the resistance encountered by fluid flowing through a pipe, usually expressed in pounds per square inch (psi).

The horizontal distance between the hands when lifting, measured center to center.

The vertical distance between the hands and the floor at the start of the lift.

The frequency of lifts per minute, limited to a maximum of 15 lifts per minute.

The angular displacement of the back during the lift, measured in degrees.

The maximum acceptable weight that can be lifted safely, based on specific lifting conditions.

A multiplier used to account for the coupling type, which describes the quality of grip and hold during a lift.

A multiplier used to account for the frequency of lifts per minute, and duration of the lifting task.

A multiplier used to account for the vertical distance of the lift, considering the distance from the ground and the lifter's height.

A multiplier used to account for the horizontal distance between the lifter's hands.

A multiplier used to account for the distance to the object's center of gravity, considering the handle's location.

A measure of the concentration of a substance in air that represents the level below which most workers can be repeatedly exposed without adverse effects, as determined by regulations.

The rate at which energy is consumed or transferred.

The lowest concentration of a flammable vapor in air that will support combustion in the presence of an ignition source. It's the point below which the mixture will not ignite.

The combined gas law equation combines Boyle's law and Charles' law. It describes the relationship between pressure, volume, and temperature of a gas. This law can be used to predict how gases behave under changing conditions.

This equation demonstrates how the total power in a circuit is calculated. Power is the rate at which energy is consumed or transferred.

A mathematical function that calculates the average of a set of numbers.

A measure of how spread out a set of data points are from the mean.

A statistical measure that shows the strength and direction of the linear relationship between two variables.

A mathematical function that calculates the product of successive positive integers down to 1.

A mathematical function that calculates the number of ways to choose a subset of elements from a set, where order doesn't matter.

A mathematical function that calculates the number of ways to order a subset of elements from a set.

A function that raises a number to a power.

A way to represent very large or very small numbers using powers of 10.

A function used to find the power to which a base must be raised to obtain a given number.

Represents the base of the natural logarithm, an important mathematical constant approximately equal to 2.71828.
