Trade Of Armaments

1.vary velocity of the pellet
valuate attainment of penetration
Keep place in the midst of gun and atomic number 13 sheets constant

2.Diagram Depth of penetration





Distance, d constant
Distance constant








Wallwall
Box

Gun

Al Sheet held between Clamps


Use this formula, V = V0e-ux

Where V = velocity
V0 = Initial velocity
U = coefficient
X = thichness of aluminium sheet

-use aluminium sheets to vary the speed
-measure speed using lightgates or electronic timers
-Cut the side of the encase to obtain the cross section and then measure the depth of penetration

3.Plot a graph of depth of penetration against speed
4.- set experiment using safety screen
-do not point the gun at any observer in the lab
5.



Both pistol and box should be secured to avoid recoil
Measure thickness of aluminium sheet using micrometer
Use aluminium block instead of superposition of aluminium foil
Repeat to stretch error









Parachute
1.To vary preventive/diameter of canopy
To measure last velocity
To ascendance diameter/load

2.Vary load using sloted weight
Measure the load using electronic balance
To vary diameter (use fan to hit the ceiling canopy to different diameter or use canopy of different diameter)
Use scale to measure diameter
Ensure that depot velocity is reached
One region of terminal velocity, use bigger distance/time
Use video-camera, electronic timer to determine terminal velocity.

3.Plot a graph of Terminal velocity against diameter and a graph of terminal velocity against load
4.Place linchpin bucket below load to ensure safety and waer poise toe shoes
5.perform experiment in draught light environment
ensure temperature is constant in the lab
use larger manageable distance in the labIf you want to get a plentiful essay, order it on our website: Orderessay
