To find the moment of a force about a point simply multiply the force by the perpendicular distance to the point.



To make things easier, you can break the force into horizontal and vertical components and sum each of their...

This video tutorial teaches the basics of drawing a human face and its proportions, with step-by-step instructions on drawing the eyes, nose, lips, and other features. It also provides tips on adjusting the parameters to create different...

In this video we will learn how to draw lines that are horizontal, vertical, diagonal, and basic shapes like rectangles, squares used for sketching.

👉 Learn how to graph piecewise functions. A piecewise function is a function which have more than one sub-functions for different sub-intervals(sub-domains) of the function's domain. To graph a piecewise function, we graph the different...

As the name might suggest, centrifugal pumps are a type of pump that operates on the principle of centrifugal force. This industrial training course on centrifugal pumps will provide you with a greater understanding of what...

👉 Learn how to graph a rational function. To graph a rational function, we first find the vertical and horizontal or slant asymptotes and the x and y-intercepts. After finding the asymptotes and the intercepts, we graph the values and...

Sketch Constraints Now in the Toolbar

With the new UI, you'll see that all of the sketch constraints are now located in the toolbar while you're in the SKETCH tab. The constraints all work in the same manner - none of the...

The resultant force vector is the vector sum of all other external forces. This can be found graphically by placing the arrows on top of each other or analytically by summing up all horizontal and vertical components.

👉 Learn how to graph absolute value equations when we have a value of b other than 1. B will affect our horizontal shift as well as horizontal stretch compress. We will do this by first identifying the axis of symmetry and using a table...

👉 Learn how to find the vertical/horizontal asymptotes of a function. An asymptote is a line that the graph of a function approaches but never touches. The vertical asymptote is a vertical line that the graph of a function approaches but...

👉 Learn how to determine the transformation of a function. Transformations can be horizontal or vertical, cause stretching or shrinking or be a reflection about an axis. You will see how to look at an equation or graph and determine the...
