Chapter 25, Problem 1R
Why are all welds not inspected to the same level or standard?
Expert Solution & Answer
To determine
The reason all welds are not inspected to the same level or standard.
Answer to Problem 1R
The quality of the weld that will pass or be acceptable for one welding application may not meet the needs of another.
Explanation of Solution
Given Information:
All welds are not inspected to same level or standard.
All welds are not inspected to the same level. The required quality of welds depends on the service which the object provides.
A high-quality weld is required in nuclear reactors, while a moderate quality of weld may work for house window.
So, the inspection of welds for nuclear reactor should higher the standards, but same standard for welds of house window will not be needed. Therefore, all the welds are not inspected to the same level or standard, rather it depends on the service of the object.

The beam ABC has a mass of 79.0 kg and is supported by
the rope BDC that runs through the frictionless pulley at D
. The winch at C has a mass of 36.5 kg. The tension in the
rope acts on the beam at points B and C and counteracts
the moments due to the beam's weight (acting vertically at
the midpoint of its length) and the weight of the winch
(acting vertically at point C) such that the resultant moment
about point A is equal to zero. Assume that rope segment
CD is vertical and note that rope segment BD is NOT
necessarily perpendicular to the beam.
a.) Compute the tension in the rope.
b.) Model the two forces the rope exerts on the beam as a
single equivalent force and couple moment acting at point B.
Enter your answer in Cartesian components.
c.) Model the two forces the rope exerts on the beam as a
single equivalent force (no couple) and determine the
