Once properly installed, a metal roofing sheet is capable of lasting as long as the house is standing for the reason that metal roofing sheet doesn’t rot or crack, neither does it warp or curl. The shingles or panels doesn’t break or split, nor can they burn and the design doesn’t peel off for ages. Metal roofing sheet seals off water, capable of surviving high winds and it can shed snow and thawing quickly. Metal also can resist fire, insects, mildew and wane.

Aluminum's advantages stem from holding its integrity for longer. Aluminium license plates don’t yellow, crack, curl, warp, or break, and they won’t rust or corrode. Screen-printed aluminum auto tags will last a minimum of 5–7 years in terms of the non-fade ink life, and often longer. With aluminum it’s more the non-fade ink life that’s of concern, since the aluminum plate itself can last 10 years or more.

The performance of the closed loop stepper system is better than the open-loop setting. Only the relationship between torque and acceleration is considered. The torque speed curve shows the peak and continuous torque range of the closed loop stepping system and the available torque range of the open loop stepping system. Usually, the actual torque will be converted into acceleration, therefore, the motor with more torque can accelerate the rated load faster.

A spy camera is a device that is capable of capturing video (and sometimes audio) of a location without the subjects' knowledge. Although they are occasionally used for commercial purposes, spy cameras are mainly used for surveillance activities. Spy cameras are also sometimes known as nanny cameras or nanny cams, due to the common use of spy cameras in checking on caregivers' treatment of children.
