In this section we will discuss four methods to specify points and vectors in three-dimensional space. The most commonly used method is an extension of two-dimensional rectangular …

This free online statics course teaches how to assess and solve 2D and 3D statically determinate problems. The course consists of 73 tutorials which cover the material of a typical statics …

The main differences are that directions are described with unit vectors rather than with angles, and moments are determined using the vector cross product rather scalar methods. Because …

Finding the parallel projections of vectors with dot projects. Computing cross products to find the rotational tendency of forces. This chapter will help you build this skillset.

In this course, we begin to focus on Engineering Statics, where we solve force systems in static equilibrium. First, we revew Newton's Laws, Units, and Trigonometry. Next, we learn how to …

Vector Statics (ME 2141) In this course, students learn how to analyze systems that are in equilibrium.

In 2-dimensions, there are two components: x and y. In 3-d, there are three components: x, y, and z. The unit vector (^u –– u ^ _) represents the direction in cartesian form ^u –– = ^i – + ^j – +^k …

2D vector variable is a special case of the general, 3D vector variable in which the third component is ignored during any operations and computations. To declare that a variable is a …

At first glance, a Statics student might try to use vector notation for this type of problem. But more experienced students would quickly notice that System I is equivalent to System II. Since the …

vectors are defined as quantities that follow the parallelogram law. = P + Q. Note: Vector addition is independent of any chosen coordinate system. Two vectors are equal if they have the same …
