what are good characteristics of a crumple zone?
344987
Crumple zones work by managing crash energy and increasing the time over which the deceleration of the occupants of the vehicle occurs, while also preventing intrusion into or deformation of the passenger cabin. This better protects car occupants against injury.

Good lime should possess the following characteristics: 1. Freedom from cinders and clinkers, with not more than 10 per cent, of other impurities. 2. It should be in hard lumps, with but little dust.

To describe a distribution with numbers we consider shape, center, and spread. These three characteristics vie a good description of the overall pattern. We already know about shape: symmetric or skewed. The most common measure of center is our ordinary arithmetic average (MEAN).

['They are composed of amino acids.', 'They have excellent absorbency.', 'Moisture regain is high.', 'They tend to be warmer than others.', 'They have poor resistance to alkalis but good resistance to acids.', 'They have good elasticity and resiliency.']

Are crumple zones effective? In a typical crash scenario, the crumple zone effectively redistributes the force of impact on the vehicle, leaving the 'safety cell' intact whilst the front or rear of the vehicle is completely deformed. This means that the crumple zone is working correctly.

Advantages. The best feature of the orbital sander is its square shape, which allows it to get in corners and up against edges. You can also use regular sandpaper cut to fit rather than purpose-made random-orbit sanding disks. Orbital sanders aren't overly aggressive, so it's hard to remove too much material.

Characteristics of Quick Breads Includes a centre crack and has an evenly browned top & crust, with well-distributed portions of fruits or nuts. Texture – Have a relatively fine crumb along with the uniform grain. Entirely free of large tunnels, and has a moist finish.
