Answer:
The calculations is shown below on the basis of equation:
work = force × distance
Explanation:
- Here the work done is 600 J and distance is certain cm ( assume 10 cm).
- As work done is the force applied for certain distance.
Mathematically,
work = force × distance
so,
force =
or, force =
or, force=
or, force = 6000 N
or, force = 6 KN
Hence taking distance as 10 cm, the force will be 6 KN.
Answer:
ω = 0.0347 rad/s²
a ≅ 1.07 m/s²
Explanation:
Given that:
mass of the model airplane = 0.741 kg
radius of the wire = 30.9 m
Force = 0.795 N
The torque produced by the net thrust about the center of the circle can be calculated as:
where;
F represent the magnitude of the thrust
r represent the radius of the wire
Since we have our parameters in set, the next thing to do is to replace it into the above formula;
So;
(b)
Find the angular acceleration of the airplane when it is in level flight rad/s²
where;
I = moment of inertia
ω = angular acceleration
The moment of inertia (I) can also be illustrated as:
I = ( 0.741) × (30.9)²
I = 0.741 × 954.81
I = 707.51 Kg.m²
Making angular acceleration the subject of the formula; we have;
ω =
ω = 0.0347 rad/s²
(c)
Find the linear acceleration of the airplane tangent to its flight path.m/s²
the linear acceleration (a) can be given as:
a = ωr
a = 0.0347 × 30.9
a = 1.07223 m/s²
a ≅ 1.07 m/s²
Answer: a hydraulic machine has water or air controlled by pistons that are airtight, water does great forces and air when compressed or squeezed to make things move, take a CAT machine for example (if you live in america, its those big yellow trebuchets or cranes) they use a piston for the arm and in front of those pistons you have mainly water (if your using a CAT machine) and those pistons push the water to and from your machines arm to create movement.
as you can see, in this picture, the CAT has hydraulics running against the arms of the machine
