Theresa is installing a curtain rod on the wall above the
window. In order to ensure that the rod is parallel to the ceiling, she measures
a career as an interior

these markings centered over the window, how does she know the curtain rod

CONSTRUCTION
30.
When framing a wall during a construction
project, carpenters often use a plumb line. A plumb line is a string
with a weight called a plumb bob attached on one end. The plumb
line is suspended from a point and then used to ensure that wall
studs are vertical. How does the plumb line help to find the
distance from a point to the floor?
