3. INTRODUCTION
• Golf ball mechanism: to design a project that uses a rotating crank as
the source to lift a ball and transfer it to a cup.

4. NUMERICAL METHOD
• Torque: force that can cause an object to rotate about an axis.
• The force's magnitude and the perpendicular distance
between the torque calculation point and the force
application point determine the torque produced.

5. NUMERICAL METHOD –cont…
• Stress: The restoring force per unit area of the material.
F is the restoring force measured in Newton or N.
A is the area of cross-section measured in m2.
σ is the stress measured using N/m2 or Pa.

6. METHODOLOGY
• Cut the shaft to our preferred length.
• Lathe the shaft.
• Drill the hole.
• Tap ¼ inch threats on the bottom of the shaft to clamp to base.
• Welding the sprockets to the washers.
• Machining of blocks, crank.
• Fitting the bearing to the block, attach the shaft and gears.
• Putting the chain to the system by correction of its length.

10. RESULTS AND DISCUSSIONS
• The Crank Design: to connect and rotate the sprocket gear that is
connected to another sprocket gear by the chain.
• made a horizontal crank.
• The new design handle is about 7 inches in length.
• It’s connected to the crank by a screw.

11. RESULTS AND DISCUSSIONS- cont….
• The Block Design: for the mounting for the shafts.
• consists of 2 blocks with one for the shaft of the crank (driver
shaft) and another for a driven shaft.
• includes 2 bearings (one on each side of the block) instead of
just one bearing.

12. RESULTS AND DISCUSSIONS- cont….
• The Scoop’s handle: an arm that connects the scope to the chain while
carrying the golf ball.

13. CONCLUSIONS
• Undermined several mechanical processes and each of the group
members has a fair amount of operations to carry out.
• Learned a lot in terms of different mechanical techniques and skills.
• The total design was fully constructed and is currently undergoing
testing.
