Answer:

common fate

Explanation:

The gestalt effect may be defined as the ability of our brain to generate the whole forms from the groupings of lines, points, curves and shapes. Gestalt theory lays emphasis on the fact that whole of anything is much greater than the parts.

Some of the principles of Gestalt theory are proximity, similarity, closure, symmetry & order, figure or ground and common fate.

Common fate : According to this principle, people will tend to group things together which are pointed towards or moving in a same direction. It is the perception of the people that objects moving together belongs together.

If a particle moving in a circular path of radius 5 m has a velocity function v = 4t2 m/s, what is the magnitude of its total ac

rjkz [21]

Answer:

8.62m/s²

Explanation:

the particle is experiencing both translational and circular motion

v=4t²

$a_{t}$ = $\frac{dv}{dt}$ =8t

at t=1s, $\frac{dv}{dt}$ =8(1)=8m/s²

$a_{c}$ = $\frac{v^{2} }{r}$

at t=1, v= 4(1)² = 4m/s

$a_{c}$ =4²/5

$a_{c}$ =3.2m/s²

∴ magnitude of total acceleration, a

a= $\sqrt{a_{t} ^{2} + a_{c} {2} }$

a= $\sqrt{8^{2} +3.2^{2} }$

a= $\sqrt{64+10.24}$

a= $\sqrt{74.24}$

a=8.62m/s²

8.26 Three identical fatigue specimens (denoted A, B, and C) are fabricated from a nonferrous alloy. Each is subjected to one of

Elis [28]

Answer:

Fatigue lifetimes will be ranked as B>A>C

Explanation:

Start by calculating the mean stress for all samples

σa= (σamax + σamin)/2 = (450 - 350)/2 = 50MPa

σb= (σbmax + σbmin)/2 = (400 - 300)/2 = 50MPa

σa= (σcmax + σcmin)/2 = (340 - 340)/2 = 0MPa

Now calculate the stress amplitudes of all three samples

σa= (σamax - σamin)/2 = (450 + 350)/2 = 400MPa

σb= (σbmax - σbmin)/2 = (400 + 300)/2 = 350MPa

σc= (σcmax - σcmin)/2 = (340 + 340)/2 = 340MPa

The mean stress of samples A and B is the same which is higher than sample C. Hence samples A and B will have a higher fatigue life than sample C. However, the higher stress amplitude means lower fatigue life, hence, sample B will have a higher fatigue life than sample A. So the order will be B> A> C.

Attached picture shows the justification using and S- N plot.
