Lucia is playing with magnetic toy vehicles. She has two identical toy vehicles (purple and pink) that start on opposite sides o

Answer:

1. The potential energy of the two vehicles increased because we could observe that they have unlike poles moving towards the center of the magnet. So the magnet field would be repealing both toy vehicles.

2. The potential energy of the pink vehicle change more than the purple vehicle. This is evident as we notice the pink vehicle is closer to the center of the magnet than the other.

3. The reason for this is because Lucia exerts more force (potential energy) on the pink vehicle to fight the repelling effect of the magnet

Incomplete question. The remaining part of the question read;

How did the potential energy of the two vehicles change? Did the potential energy of one vehicle change more than the other? Why do you think so?

<u>Explanation:</u>

1. The potential energy of the two vehicles increased because we could observe that they have unlike poles moving towards the center of the magnet. So the magnet field would be repealing both toy vehicles.

2. The <u>potential energy of </u><u>the pink vehicle</u><u> change more than </u><u>the purple vehicle.</u> This is evident as we notice the pink vehicle is closer to the center of the magnet than the other.

3. The reason for this is because Lucia exerts more force (potential energy) on the pink vehicle to fight the repelling effect of the magnet

A bar of 75 mm diameter is reduced to 73mm by a cutting tool while cutting orthogonally. If the mean length of the cut chip is 7
barxatty [35]

Answer:

r=0.31

Ф=18.03°

Explanation:

Given that

Diameter of bar before cutting = 75 mm

Diameter of bar after cutting = 73 mm

Mean diameter of bar d= (75+73)/2=74 mm

Mean length of uncut chip = πd

Mean length of uncut chip = π x 74 =232.45 mm

So cutting ratio r

Cutting\ ratio=\dfrac{Mean\ length\ of cut\ chip}{Mean\ length\ of uncut\ chip}

r=\dfrac{73.5}{232.45}

  r=0.31

So the cutting ratio is 0.31.

As we know that shear angle given as

tan\phi =\dfrac{rcos\alpha }{1-rsin\alpha }

Now by putting the values

tan\phi =\dfrac{rcos\alpha }{1-rsin\alpha }

tan\phi =\dfrac{0.31cos15 }{1-0.31sin15 }\

  Ф=18.03°

So the shear angle is 18.03°.

B1) 20 pts. The thickness of each of the two sheets to be resistance spot welded is 3.5 mm. It is desired to form a weld nugget
kap26 [50]

Answer:

minimum current level required =  8975.95 amperes

Explanation:

Given data:

diameter = 5.5 mm

length = 5.0 mm

T = 0.3

unit melting energy = 9.5 j/mm^3

electrical resistance = 140 micro ohms

thickness of each of the two sheets = 3.5mm

Determine the minimum current level required

first we calculate the volume of the weld nugget

v = \frac{\pi }{4} * D^2 * l = \frac{\pi }{4} * 5.5^2 * 5 = 118.73 mm^3

next calculate the required melting energy

= volume of weld nugget * unit melting energy

= 118.73 * 9.5 = 1127.94 joules

next find the actual required electric energy

= required melting energy / efficiency

= 1127 .94 / ( 1/3 )  = 3383.84 J

TO DETERMINE THE CURRENT LEVEL REQUIRED  use the relation below

electrical energy =  I^2 * R * T

3383.84 / R*T = I^2

3383.84 / (( 140 * 10^-6 ) * 0.3 ) = I^2

therefore  8975.95 = I ( current )
