As speed increases, the elements of your stopping distance, and therefore what's your stopping distance as a whole ?

1 answer:

5 0

<span>There are many factors that can affect the stopping distance, a set of things that can be named as important factors that make up the decision to stop at increased speed. The first factor is human, which can be affected by fatigue, distraction, alcoholism, among others, but the 4 key components of stop distance are: Time perception, Time reaction, Vehicle reaction, Braking capacity.</span>

lord [1]

Answer:

The speed of light will be c=3x10^8m/s

Explanation:

This is the same as the speed of light because your speed does not affecttje speed of light so you will see the light approaching you at the same speed of light c

A single crystal of aluminum is oriented for a tensile test such that its slip plane normal makes angle of 28.1 with the tensil

NISA [10]

Answer:

we have to find out the critical resolved shear stress. As it it given in the question

Ф = 28.1°and the possible values for λ are 62.4°, 72.0° and 81.1°.

a) Slip will occur in the direction where cosФ cosλ are maximum. Cosine for all possible λ values are given as follows.

cos(62.4°) = 0.46

cos(72.0°) = 0.31

cos(81.1°) = 0.15

Thus, the slip direction is at the angle of 62.4° along the tensile axis.

b) now the critical resolved shear stress can be find out by the following equation.

τ $_{crss}$ = σ $_{Y}$ ( cosФ cosλ) $_{max}$

now by putting values,

= (1.95MPa)[ cos(28.1) cos(62.4)] = 0.80 MPa (114 Psi) 7.23
