Answers

Answer 1

A) Constant angular acceleration of wheel, α= 42.5 rad/s²  B)ω= 191 rad/sec   C)ω= 335.5 rad/sec   D)Ф = 895.05 rad  E)t = 6.09 sec

What is angular acceleration?

Angular acceleration is a quantitative expression of the change in angular velocity of spinning object  per unit time.

A)Given a= 10.2 m/s^2 and radius= 0.240m

α= a / r

= 10.2/0.240

α= 42.5 rad/s²

The constant angular acceleration of the wheel is 42.5 rad/s².

B)The tangential speed v is

v = vt + a ( t -t0)

= 54 + (-10.2)(3.40 - 2.60)

= 54- 8.16

v= 45.84 m/s

angular velocity is

ω= v / r

= 45.84/0.240

ω= 191 rad/sec

C) Angular Velocity at t=0:

tangential speed v is

v = vt + a ( t -t0)

= 54 + (-10.2)(0 - 2.60)

= 80.52 m/s

angular velocity is given as,

ω= v / r

= 80.52/0.240

ω= 335.5 rad/sec

D)Angle at wheel turned is calculated by the formula :

Ф = ωΔt + 1/2 *α (Δ t)²

Δt =  3.4 - 0= 3.40

Ф= (191 * 3.4) +1/2* 42.5 * (3.4)²

=649.4 + 245.65

Ф = 895.05 rad

E)Radial acceleration is equal to the acceleration due to gravity and can be written as,

α1= ω2 r

ω2 = √g/r

= √9.8/0.240

= 6.39 rad/sec

time taken by the wheel to reach from  ω to ω2 is calculated as

ω2 = ω+αt

t= (ω2- ω)/t

= 6.39- 335.5 / -54

= 329.11/-54

t = 6.09 sec

Saturn is the second-largest planet in our solar system and is located six planets from the Sun. Saturn is an enormous ball primarily composed of hydrogen and helium. There are other planets that have rings, but none are as beautiful or intricate as Saturn's. Numerous moons orbit Saturn.The Saturn system is a rich source of scientific discovery and still holds many mysteries, from the water jets that spray from Saturn's moon Enceladus to the methane lakes on smoggy Titan.

Clouds that resemble faint stripes, jet streams, and storms cover Saturn. The planet has a wide range of yellow, brown, and gray hues.

The equatorial region experiences winds that can reach 1,600 feet per second (500 meters per second) in the high atmosphere. The highest hurricane-force winds on Earth, however, only reach a maximum speed of roughly 360 feet per second (110 meters per second). And because of the intense pressure, which is similar to that experienced while diving deep underwater, gas is compressed into liquid.

An intriguing atmospheric phenomenon on Saturn's north pole is a six-sided jet stream. The hexagon, a wavy jet stream with winds of 200 miles per hour (322 kilometers per hour), is around 20,000 miles (30,000 kilometers) broad and has a large rotating storm at the center.

We are given the following Important parameters or information or data which is going to assist us in order to solve this question effectively and efficiently.

Jy = 500 Nm, Jb = 10 KNm, wy = 60 KN, wx = -80 KN.

Thus, I(bb) = 10/12 × 100 × (200 + 2 × 20)^3 - 1/2 (100 - 20) × 200^3.

l(bb) = 6.19 × 107 mm^4.

l(yy) = 1/12 × 20 × 240^3 × 2 + 1/2 × 200 × 20^3.

l(yy) = 4.62 × 10^7 mm^4.

Thus, the bending stress due to Jy = Jy × y / l(bb)

The bending stress due to Jb;

=> 500 × 10^ 6 ×( 200/2)/ 6.19 × 10^7 = 16.16 MPa.

The bending stress due to wx = wx/A= -80/800 = 10 MPa.

Transverse shear stress = 60 × 10^3 × 220000/ 6.19 × 10^ 7 × 20 = 10.66 MPa.

Answers

Ray consumes 2400 kcal per day and expends 2400 kcal per day is the following individuals is in energy balance (equilibrium).

What is energy balance?

Energy balance is the condition that is reached when energy intake and energy usage are equal. This idea can be used to show how variations in energy intake and expenditure will cause changes in body weight over time. Bodyweight is steady when the body is in a state of energy balance.

What is Equilibrium?

In physics, a system is said to be in equilibrium when neither its internal energy state nor its state of motion tend to vary over time. If a simple mechanical body experiences neither linear acceleration nor rotational acceleration, it is said to be in equilibrium. If this state is not disturbed by an external force, it will persist unbrokenly.

A stone of mass 10kg fall from the height of 2m.calculate the workdone​

Answers

The work done is 196 J.

The amount of work done upon an object depends upon the amount of force (F) causing the work, and the displacement (d) experienced by that object.

The mass of the stone is m=10kg

It is falling from the height of 2m i.e. its displacement is 2m.

Work done by an object is given by:

W=Fs

Where 'F' is the force and 's' is the displacement.

As the body moves in the direction of force, therefore work done by gravitational force will be positive.

W = Fs

    = mgh

    = 10 × 9.8 × 2

    = 196 J

Hence, the work done is 196 J.
