Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.

Question

**Problem Statement:**

The spring-toggle system is in the vertical plane and is held at rest with \( \theta = 45^\circ \) when a moment of \( 12 \, \text{N} \cdot \text{m} \) is applied at point \( C \). In the initial position, the spring, with stiffness of \( 140 \, \text{N/m} \), is stretched \( 150 \, \text{mm} \). Bar \( AB \) has a mass of \( 3 \, \text{kg} \), and bar \( BC \) has a mass of \( 6 \, \text{kg} \). Find the angular velocity of \( BC \) at the moment when \( \theta = 0 \). Neglect friction effects.

**Diagram Explanation:**

The diagram accompanying the problem statement shows a mechanical system composed of two bars and a spring:

- Bar \( AB \) is connected to a fixed point \( A \) and is 250 mm in length.
- Bar \( BC \) is connected to bar \( AB \) at point \( B \) and is also 250 mm in length.
- A spring is attached between the ground and point \( B \) on bar \( AB \).
- Point \( C \) is located at the end of bar \( BC \), where the moment is applied.
- The system is shown with the angle \( \theta \) denoting the angle between bar \( AB \) and the vertical axis.

The illustration helps visualize the problem setup for solving the angular velocity of bar \( BC \).

The 250-kg wheel has a radius of gyration about its center O of ko = 260 mm, and radius r = 0.4 m. When the wheel is subjected to the constant couple moment M = 64 N.m, it starts rolling from rest. Determine the total angular impulse L (in N.m.s) about the wheel's IC after 7.3 seconds if the wheel has been rolling without slipping. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point. Take g = 9.81 m/s². M Your Answer: Answer
The 150 kg spool below is initially at rest and has a radius of gyration of kg 0.5 m. The force Pis applied at B and causes the spool to begin rotating. The rope attached to point A does not slip at its contact point with the spool, meaning that point is an instantaneous center of zero velocity as shown. However, the bottom of the spool slips against the ground, causing a frictional force which acts to the right. After 5 s the angular velocity of the spool is -27 rad/s (using the coordinate system shown, meaning the spool rotates in the clockwise direction). Based on this information: a) Find the moment of inertia of the spool at the instantaneous center of zero velocity. b) Calculate the frictional force exerted on the spool by the ground. c) Using the principal of angular impulse and momentum, determine the coefficient of kinetic friction, r, between the bottom of the spool and the ground.
