54-(15x2) divided by 2 = 12
54 - 15 = 39
39-15=24
24 divided by 2=12
Length:15
Width:12
Perimeter:54
Answer:
To reverse all types of defects.
Explanation:
In the magnetic particle inspection method the material which is used in testing will utilize the magnet which is ferromagnetic and it is high permeable and the retentivity of this magnet is low.
It is a technique which is not destructive and this technique is used for detecting the surface and the hollow part of ferromagnetic substance and will reverse all these defects.
Therefore, circular and longitudinal way of magnetization will reverse all the types of defect.
1) Inertia causes the person to keep going when the vehicle stops, so if you're not wearing a seatbelt you'll keep going until you hit something. Whether that be the seat ahead, the windshield, or the road.
2) It takes 4 times as long to stop a vehicle going twice the speed.
3) A large vehicle takes longer to stop because there's more mass and more kinetic energy there.
4) To prepare to enter sharp curves, a driver should slow down before turns
Answer:
Explanation:
Taking torque about the fulcrum of all forces , for rotational equilibrium ,
6 x 5 + 2 x ( 7-5 ) = 10 x d
= 30 + 4 = 10 d
d = 3.4 m .
