Question

Consider the window crank below - note that its components are not necessarily orthogonal. Given the following:

What angle does it make with the x-axis?
a) Lies in the yz plane
b) Lies in the xy plane
c) 90 degrees
d) Depends on the specific configuration

Answer 1

The angle a window crank makes with the x-axis depends on its orientation. If it's in the yz-plane, the angle is 90 degrees. In the xy plane, the angle depends on its specific configuration.

Step-by-step explanation:

The question pertains to the angle a window crank makes with the x-axis. The options suggest different positions the crank might have relative to the coordinate system. To determine the angle correctly, we must first understand the orientation of the crank. If the crank lies in the yz-plane, it is orthogonal to the x-axis and thus makes a 90-degree angle with it. If it lies in the xy plane, the angle depends on its specific configuration in that plane. In general, the angle between a line and a plane or the x-component of a vector is determined using trigonometric functions. For instance, the components of a vector on the xy plane would be defined using the equations Ax = A cos θ and Ay = A sin θ, where θ is the angle the vector makes with the x-axis.
