Answer:
2.5kN.m
Explanation:
Torque is directly proportional to pitch diameter
= Ta/Tb= Da/Db
=120/Tb= 0.25/0.5
Tb= 2.469kN.m approx 2.5kN.m
Answer:
Explanation:
Given data
For Part (a) Speed
The speed v is given by
For Part (b) minimum coefficient of friction
To determine the friction of coefficient we know that friction force f is given by:
The first centripetal force Fc₁ is given by:
The second centripetal force Fc₂ is given by:
The additional friction force is given by:
Answer:
The mass of the body is 2.2 kg.
Explanation:
Given that,
Force acting on a body 1,
Force acting on a body 2,
Direction,
Acceleration,
To find,
Mass of the body.
Solution,
Let F is the net force acting on the body. It is given by :
F = 43.22 N
Second law of motion is given by :
F = ma
m = 2.16 kg
or
m = 2.2 kg
So, the mass of the body is 2.2 kg.
Answer:
Explanation:
In space station artificial gravity is created by rotational motion of space station
Centifugal acceleration creates artificial gravity
ω²r = g
ω² x 400 = 9.8
ω² = 9.8 /400
ω = .1565 rad /s
no of turns per min ω / 2π per sec = 1.56 rev per min .
For Mars
Same theory will apply
ω²r = g
ω² x 400 = 3.7
ω² = 3.7 /400
ω = . 096 rad /s
n = ω / 2π
= .096 / 2π
=.01528 per sec
per min
= .9168 per min .
