20870 Vector polygon to solve for the forces on a block in equilibrium on a plane.
A block whose weight is W= 250 nt is on a frictionless plane which is at angle q= 25 degrees.

relative speed and angular velocity
Solve the relative velocity equations using :
A a vector polygon
B vector algebra
Please see the attached file. It determines the angular velocity of the link by solving the relative velocity equations using two differential methods.

Vector solution of a ring in equilibrium with three acting forces.
Draw (not to scale) the known vectors A and B head to tail, then complete a closed polygon with vector C. Using given information, show all known magnitudes and angles. See ATTACHMENT2.
Step 2.

Vector A in polar coordinates, vector B in unit vectors: Find vector sum difference.
Vector A= 5 units at 53 degrees, and B= 5 i  2 j in which i and j are unit vectors in x and y directions respectively.
PART a. Show A and B and vector sum C in a polygon (Not to scale) showing A + B = C.

Solution of Relative Velocity Problem
Carefully observe the problem attachment, a picture illustrating all given
information in Fig. 1.
a. Find the magnitude and direction of
actual velocity vector A.
b. Construct a polygon connecting vectors
W, B, and A.

Physics: Two pulley tension problem
The vector sum can be found by either of two methods
Method #1: The given force vectors are drawn to scale, connected head to tail thus forming two sides of a polygon.

Boat leaves one bank of a river so as to arrive downstream across river.
The actual velocity of a boat over the ground, is the vector sum of two velocities: the velocity of the river, and the velocity of the boat relative to the water. In this example, we can write:
(2) vector S = vector W + vector B
Step 3.

Finding the Area of a Parallelogram
A(1,2,2), B(1,3,6), C(3,8,6), and D(3,7,3)
(a) For triangle ABD,
Thus, the area of the triangle ABD is
(b) For triangle CBD
Thus, the area of the triangle ABD is
Therefore, the area of the polygon is The area of a parallelogram
