What is the key to preventing accidents in a welding shop?
Expert Solution & Answer
To determine
The key to prevent accidents in a welding shop.
Explanation of Solution
The key to prevent accidents in a welding shop are:
- Necessary protection must be taken while welding process otherwise it will harm the welder.
- Safety precautions must be taken. The safety precautions are mentioned on the manual of every equipment.
- There is no substitute to caution and common sense so each person take personal responsibility for their own safety and safety of others on the job.
- Follow all the safety rules, regulation and procedure of welding areas.
- Never engage in horseplay or practical jokes while at work.

A crate weighs 530 lb and is hung by three ropes attached to
a steel ring at A such that the top surface is parallel to the
xy plane. Point A is located at a height of h = 42 in above
the top of the crate directly over the geometric center of the
top surface. Use the dimensions given in the table below to
determine the tension in each of the three ropes.

A block of mass m hangs from the end of bar AB that is 7.2
meters long and connected to the wall in the xz plane. The
bar is supported at A by a ball joint such that it carries only a
compressive force along its axis. The bar is supported at end
B by cables BD and BC that connect to the xz plane at
points C and D respectively with coordinates given in the
figure. Cable BD is elastic and can be modeled as a linear
spring with a spring constant k = 400 N/m and unstretched
length of 6.34 meters.
Determine the mass m, the compressive force in beam AB
and the tension force in cable BC.
