What standard feature is on all circular saws?

Technician A says that a part is considered bent if it has a sharp bend with a small radius over a short distance. Technician B

zhuklara [117]

In the above case with Technician A and B, non of them are correct in what they have said.

This is known to be a sharp bend that is known to have a little radius over a short distance.

A Bend is said to be the slow alteration or change in shape that exist between the damaged and undamaged area.

Therefore, looking at the definition, you can see that In the above case with Technician A and B, non of them are correct in what they have said.

The speed of a vehicle is reduced with a constant acceleration from 72km/h to 18

Radda [10]

Answer:

The correct answer will be "1477.84 N".

Explanation:

Given that,

Mass,

m = 1.6 mg

or,

= 1600 kg

Initial velocity,

u = 72 km/h

= $72\times \frac{5}{18} \ m/s$

= $20 \ m/s$

Final velocity,

v = 18 km/h

= $18\times \frac{5}{18}$

= $5 \ m/s$

Covered distance,

s = 250 m

By using the below relation, we get

⇒ $v^2=u^2+2as$

On putting the values, we get

⇒ $(5)^2=(20)^2+2\times a\times 250$

⇒ $a=-0.75 \ m/s^2$ (shows the deceleration)

Slope will be given as 1 in 25, then

⇒ $Sin \theta=\frac{1}{25}$

$\theta=2.3^{\circ}$

hence,

As we know,

⇒ $\Sigma F=ma$

or,

⇒ $Braking \ force+350-mgSin\theta=ma$

⇒ $Braking \ force=ma+mgSin\theta-350$

On substituting all the values, we get

⇒ $=1600(0.75+1600\times 9.81 Sin(2.3^{\circ})-350$

⇒ $=1477.84 \ N$

The 5-kg collar has a velocity of 5 m>s to the right when it is at A. It then travels along the smooth guide. Determine its s

Gnoma [55]

Answer:

The speed at point B is 5.33 m/s

The normal force at point B is 694 N

Explanation:

The length of the spring when the collar is in point A is equal to:

$lA=\sqrt{0.2^{2}+0.2^{2} }=0.2\sqrt{2}m$

The length in point B is:

lB=0.2+0.2=0.4 m

The equation of conservation of energy is:

$(Tc+Ts+Vc+Vs)_{A}=(Tc+Ts+Vc+Vs)_{B}$ (eq. 1)

Where in point A: Tc = 1/2 mcVA^2, Ts=0, Vc=mcghA, Vs=1/2k(lA-lul)^2

in point B: Ts=0, Vc=0, Tc = 1/2 mcVB^2, Vs=1/2k(lB-lul)^2

Replacing in eq. 1:

$\frac{1}{2}m_{c}v_{A}^{2}+0+m_{c}gh_{A}+ \frac{1}{2}k(l_{A}-l_{ul}) ^{2}=\frac{1}{2}m_{c}v_{B}^{2}+0+0+\frac{1}{2}k(l_{B}-l_{ul}) ^{2}$

Replacing values and clearing vB:

vB = 5.33 m/s

The balance forces acting in point B is:

Fc-NB-Fs=0

$\frac{m_{C}v_{B}^{2} }{R}-N_{B}-k(l_{B}-l_{ul})=0$

Replacing values and clearing NB:

NB = 694 N

What is the function and role of product tear down charts, and how do engineers utilize them in the reverse engineering process?

lora16 [44]

Answer:

Product Teardown 28 pieces (1) Plastic packaging: protect and display product for purchase. (4) Exterior screws: hold case halves together. (1) Right case half: acts as part of a handle and contains the rest of the parts. (1) Left case half: acts as part of a handle and contains the rest of the parts.

Explanation:

A product teardown process is an orderly way to know about a particular product and identify its parts, system functionality to recognize modeling improvement and identify cost reduction opportunities. Unlike the traditional costing method, tear down analysis collects information to determine product quality and price desired by the consumers.
