What is your design for an efficient commercial vehicle chassis that incorporates as many commercial truck components into its s
Crank

The design that would be used to make an efficient commercial vehicle chassis that has many realistic truck components is:

  • Strength
  • Adequate bending stiffness
  • Maximum stress
  • Deflection, etc

<h3>What is a Chassis Frame?</h3>

This refers to the main vehicle structure of a car that bears all the main stress that other components are attached to.

Hence, we can see that to make a good design for an efficient commercial vehicle chassis that has many realistic truck components, we would have to consider various factors such as handling maximum stress, maximum equilateral stress, and deflection.

A box of mass 3.6 kg is lifted 5.4 m above the
horsena [70]

So, the energy change that occurs is 190.512 J.

<h3>Introduction</h3>

Hello ! I am Deva from Brainly Indonesia will help you regarding energy and its transformation. In this case, it's the use of energy from the lifter to be equivalent to the change in the object's potential energy. Why potential energy? Because the box undergoes a change in height and the potential energy specializes at a certain height. Work (W) due to change in potential energy (\sf{\Delta PE}) can be realized in the equation :

\sf{W = \Delta PE}

\sf{W = m \cdot g \cdot h_2 - m \cdot g \cdot h_2}

\boxed{\sf{\bold{W = m \cdot g \cdot (h_2 - h_1)}}}

With the following condition :

  • W = work of subject (J)
  • \sf{\Delta PE} = change of potential energy (J)
  • m = mass (kg)
  • g = acceleration of the gravity (m/s²)
  • \sf{h_2} = final height (m)
  • \sf{h_1} = initial height (m)

<h3>Problem Solving</h3>

We know that :

  • m = mass = 3.6 kg
  • g = acceleration of the gravity = 9.8 m/s²
  • \sf{h_2} = final height = 5.4 m
  • \sf{h_1} = initial height = 0 m

What was asked :

  • W = work of subject = ... J

Step by step :

\sf{W = \Delta PE}

\sf{W = m \cdot g \cdot (h_2 - h_1)}

\sf{W = 3.6 \cdot 9.8 \cdot (5.4 - 0)}

\sf{W = 3.6 \cdot 9.8 \cdot 5,4}

\boxed{\sf{W = 190.512 \: J}}

So, the energy change that occurs is 190.512 J.

A proton with an initial speed of 400,000 m/s is brought to rest by an electric field. Did the proton move into a region of high
Anton [14]

A proton is initially moving at high speed

v = 400000 m/s

so here initially proton is having high speed and high kinetic energy

now this proton comes to rest by external electric field

so the potential energy of proton will increase or we can say that kinetic energy will convert into electrostatic potential energy

so here the proton must have to move at higher potential region

so here correct answer must be

b. Because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.

A fluid moves through a tube of length 1 meter and radius r=0.002±0.0002 meters under a pressure p=4⋅105±1750 pascals, at a rate
yaroslaw [1]

Answer:

The  maximum error is  \Delta  \eta  = 2032.9

Explanation:

From the question we are told that

     The length  is  l  =  1\ m

      The radius is  r =  0.002 \pm  0.0002 \ m

        The pressure is  P  =  4 *10^{5} \ \pm 1750

        The  rate  is  v =  0.5*10^{-9} \ m^3 /t

       The viscosity is  \eta  =  \frac{\pi}{8} * \frac{P *  r^4}{v}

The error in the viscosity is mathematically represented  as

       \Delta  \eta  = | \frac{\delta \eta}{\delta P}| *  \Delta  P   +    |\frac{\delta \eta}{\delta r} |*  \Delta  r +  |\frac{\delta \eta}{\delta v} |*  \Delta  v

   Where  \frac{\delta \eta }{\delta P} =  \frac{\pi}{8} *  \frac{r^4}{v}

and         \frac{\delta \eta }{\delta r} =  \frac{\pi}{8} *  \frac{4* Pr^3}{v}

and          \frac{\delta \eta }{\delta v} =  - \frac{\pi}{8} *  \frac{Pr^4}{v^2}

So  

             \Delta  \eta  = \frac{\pi}{8} [ |\frac{r^4}{v}  | *  \Delta  P   +    | \frac{4 *  P * r^3}{v}  |*  \Delta  r +  |-\frac{P* r^4}{v^2}  |*  \Delta  v]

substituting values

            \Delta  \eta  = \frac{\pi}{8} [ |\frac{(0.002)^4}{0.5*10^{-9}}  | *  1750   +    | \frac{4 *  4 *10^{5} * (0.002)^3}{0.5*10^{-9}}  |*  0.0002 +  |-\frac{ 4*10^{5}* (0.002)^4}{(0.5*10^{-9})^2}  |*  0 ]

  \Delta  \eta  = \frac{\pi}{8} [56  +  5120 ]

   \Delta  \eta  = 647 \pi

    \Delta  \eta  = 2032.9
