Also, in the slope intercept form, y=mx+b, m is equal to the slope. y2-y1/x2-x1 are the coordinates that you use to figure out the slope. B stands for the y-intercept. Y and x in the slope intercept form are only variables that you plug in from your points on the cortesian coordinate plane.
Contraction joint. c. Construction joint. Out of these Expansion joint and Contraction joints are stress relieving ones while the construction joint is not. Joints can be vertical or horizontal. Vertical joint in a building is at the beam bottom of the column and wall junctions. These joints-Expansion and contraction joints separate the structures and pavements Careful preplanning the location is important for minimum crack free structural members.
A joint or articulation is the connection made between bones in the body which link the skeletal system into a functional whole. They are constructed to allow for different degrees and types of movement. Some joints, such as the knee, elbow, and shoulder, are self-lubricating, almost frictionless, and are able to withstand compression and maintain heavy loads while still executing smooth and precise movements. Other joints such as sutures between the bones of the skull permit very little movemen
