6. Introduction
The C-clamp is a simple but essential tool for any workshop. It is used to hold objects
together securely for a variety of tasks, such as woodworking, metalworking, auto
repair, construction, and DIY projects.C-clamps are made up of a curved frame, a
threaded screw, and a movable jaw. The jaw is tightened against the workpiece by
turning the screw, which creates a strong grip. C-clamps come in a variety of sizes and
styles, but they all work in the same basic way.
When using a C-clamp, it is important to make sure that the movable jaw is positioned
evenly on the workpiece. This will help to ensure that the clamp applies even pressure
and does not damage the workpiece. It is also important to use the right size C-clamp
for the job. If the clamp is too small, it will not be able to apply enough pressure to hold
the workpiece in place. If the clamp is too large, it may damage the workpiece.

24. Conclusion:
In this project As per BIS 1570(Part 2) - 1379 . I used 35C4 steel material for its design
and analysis. As per the FEA analysis, I found the FOS = 1 for 30 KN load , so its
maximum load capacity is 30 KN. For load 7KN its FOS = 3.3.
For increasing its load capacity we can increase its fillet radius.
