To solve this problem it is necessary to apply the concepts related to internal torque, shear stress and the angle generated from the modulo of elasticity, torque, length and polar moment of inertia.
We will start by finding the angular velocity in units that allow us to find the total torque:
From the indicated variable of power, in English system this would be
With the power and angular velocity found, the torque would then be:
The torsion formula will allow us to find maximum stress due to the shear force acting on the body:
And finally the angle of twist
Therefore the anle of twist in the shaft at full power is 4.58°
<span>The correct option is C. Energy cannot be created or destroyed. This statement is known as law of conservation of energy, and it implies that whenever a certain form of energy does change, the loss of this form of energy must have converted into an another type of energy. A typical example is an object falling to the ground: initially, the object has gravitational potential energy. As the object falls down, it loses potential energy (since its altitude from the grounf decreases), but it acquires kinetic energy (because its velocity increases). In this example, potential energy has converted into kinetic energy, but the total energy of the object has remained constant.</span>
Physiology is the study of all living creatures
R=U/I so R= 7V/0.5A = 14 Ω
Now we just substract botg resistors from the total to get R3: 14 - 4 - 1= 9Ω
Linear momentum is a vector quantity defined as the product of an object’s mass and it's velocity
