Answer:
3.) 0.3 m
Explanation:
Given parameters:
Torque = 40Nm
Force = 133N
Unknown:
Distance from the nut that the mechanic must apply the force = ?
Solution:
Torque is the force that causes an object to rotate on its axis;
Torque = force x distance
Distance = = 0.3m
In this problem, you are asked to find a vertical position of a ball when you are given its initial position on a spring. In both locations, the speed of the ball is zero.
If non-conservative forces are either known or small and if energy is converted from one form to another between the locations, then any time you relate speed and position of an object at two different points, conservation of energy is the most direct way to understand the problem.
In this case, you start out with stored energy in the compression of the spring and convert it to stored gravitational energy.
Answer:
Stretching vibration and bending vibration
Explanation:
1. Stretching vibration results in the variation of the bond length. There are two types of stretching vibration:
- In asymmetric bending, bonds move in and out as a result of the vibration.
- In symmetric bending, bonds move such that the bond length either gets shorter or longer.
2. Bending vibration results in the variation of the bond angle.
These can be grouped into 4 types:
- Rocking- It is that motion in which two atoms are in the motion like that of the motion of a pendulum of a clock.
- Scissoring- The motion of to atoms either away from each other or towards each other.
- Twisting- It is where the motion of the two atoms resembles that of the motion on a treadmill.
- Wagging- It is the motion in V- shape in the back and forth direction.
