Answer:
Input force is the initial force used to get a machine to begin working. Machines are designed to increase the input force for a larger output force. The quality of a machine is measured by mechanical advantage. The mechanical advantage is the ratio of the output force to the input force.
Explanation:
Answer:
The velocity is 19.39 m/s
Solution:
As per the question:
Mass, m = 75 kg
Radius, R = 19.2 m
Now,
When the mass is at the top position in the loop, then the necessary centrifugal force is to keep the mass on the path is provided by the gravitational force acting downwards.
where
v = velocity
g = acceleration due to gravity
Answer:
470 N.
Explanation:
Using equations of motion:
S = vi*t + 1/2*(a*(t^2))
Given:
S = 0.65 m
t = 1.5 s
vi = 0 m/s
0.65 = 1/2 * (a * (1.5)^2)
a = 1.3/2.25
= 0.578 m/s^2
Force = mass * acceleration due to gravity
= 92 * 0.578
= 53.16 N
Total force = 420 + 53.16
= 473.16 N
= 470 N.
Let us assume that W is the width of the border tile (with the units of ft.). Also, let A be the are which is equivalent to 296 sqft.
<span>We establish this mathematical equation:
(28+2W)(42+2W)−28×42=296
</span>
Then algebraically manipulate:(14+W)(21+W)−14×21=74
<span>W2+35W−74=0</span>
Lastly, we factor:
(W+37)(W−2)<span>=0
</span>W=2
Transformers are bots that "transform" into cars and giant mega robots. Im personally not a big fan of transformers but it is called transformers because it can transform into other non-living objects. <span />
