Nov 25, 2015 · Torsion bar mechanism After picking 24. Velocity and acceleration of projectile The velocity is continuously varying through out the projectile movement. Acceleration of projectile occupies only 0.007 sec. Retardation of projectile takes longer time and projectile Projectile Loom |Different Parts Of A Projectile Weaving Different Parts Of A Projectile Weaving Machine:Projectile loom is consist of different parts which facilities the weaving process. To make smooth the process one should know about the different parts of projectile weaving machine. Here, I have mentioned the different parts of projectile loom. They are-Fig:Projectile Weaving machine. Torsion bar Projectile Weaving Machine _ Mechanism and Working Projectile weaving machine Main parts of Projectile Weaving Machine:Torsion bar A:As shown in fig-2 it has splinted ends as seen in the fig one end is secured firmly at the clamping flange with provision for adjusting twisting angle. The twisting length of the torsion is 721 mm. It is diameter is 15, 17 or 19 mm depending upon the model.
