- investigating resistance of a wire introduction this investigation is about find the resistance of a wire resistance is the slow-down of the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. Do different types of materials affect air resistance differently which types of materials have the greatest affect on air resistance air resistance is a crucial factor when designing a parachute. An investigation of the radiation resistance of polymer based electro-optic modulators was conducted by the international photonics consultants, inc, for the air force research laboratory photonics technology branch (sndp. Numerical investigation on ballistic limit velocity of armour materials suresh fibers, and their resistance to ballistic impact was investigated for the same number of plies and weight, tried different materials with different structures, like single layer plate, sandwiches, honeycomb etc.
Investigation of the nanomechanical and tribological properties 3 the human tooth is composed of different calcified tissues, namely the enamel, dentine and cementum (ratner et al, 1996) as shown in figure 1. So far, various researches have been done on effects of cement type, water to cement ratio (w/c) , , , supplementary cementitious materials , , , , polymer materials and type of aggregates , to improve normal concrete and mortar resistance against acid attacks. Investigation to measure the resistivity of graphite essay sample aim the aim of the experiment is to find out the resistivity of graphite the resistance which is measured in ohms of a resistor is applied with three basic elements. For example, when the length of the wire is 20cm the resistance is 314 ohms when the length of the wire is 40cm the resistance is 618 ohms, which is roughly double in my main investigation i will see if this observation applies to my results. Resistance to mechanical effect of braille dot surfaces formed using screen printing on different materials (paper, paperboard, polymer, textile, al foil) was investigated it was obtained that according to the type of material, braille dot.
When beams develop a flexure-shear interaction, the shear resistance consists of two different mechanisms, beam and arch mechanisms the former governs when the a/d ratio is above the critical (transition.
