Answer: Torque T = 40.7 Nm
Explanation:
Torque or turning effect is the rotational equivalent of linear force, i.e moment of force about a point.
Given that the force is applied perpendicular to the edge (angle 90°)
Torque can be represented by T;
T = FrSin∅ = Fr ( sin90 = 1)
T = force × distance
T = F × r
F = 55N
r = 74cm = 0.74m
T = 55N × 0.74m
T = 40.7 Nm
Answer:
Explanation:
Let consider the observer as an inertial reference frame. The object is modelled after the Principle of Momentum Conservation:
The speed of the more massive piece is:
The kinetic energy added to the system is:
![\Delta K = \frac{1}{2}\cdot [(5.333\,kg)\cdot (0\,\frac{m}{s} )^{2}+(26.665\,kg )\cdot (31.202\,\frac{m}{s} )^{2}]-\frac{1}{2}\cdot (32\,kg)\cdot (26\,\frac{m}{s} )^{2}](https://tex.z-dn.net/?f=%5CDelta%20K%20%3D%20%5Cfrac%7B1%7D%7B2%7D%5Ccdot%20%5B%285.333%5C%2Ckg%29%5Ccdot%20%280%5C%2C%5Cfrac%7Bm%7D%7Bs%7D%20%29%5E%7B2%7D%2B%2826.665%5C%2Ckg%20%29%5Ccdot%20%2831.202%5C%2C%5Cfrac%7Bm%7D%7Bs%7D%20%29%5E%7B2%7D%5D-%5Cfrac%7B1%7D%7B2%7D%5Ccdot%20%2832%5C%2Ckg%29%5Ccdot%20%2826%5C%2C%5Cfrac%7Bm%7D%7Bs%7D%20%29%5E%7B2%7D)
Linear momentum is the product of mass and velocity. In this case, it is simply:
An experimental design is used to assign variables for testing. In contrast to a control design where nothing is changed, the experimental design allows you to test various new inputs to see how they would vary from the original results.
When people aboard a plane...the amount of baggage you take has to vary because the plane has a certain carrying capacity.
