Mass communication

This chapter includes the design procedure for the vibration absorber system made up of SMA springs. The vibration absorber is consisting of a mass M on which we mounted a bracelet which is made up of four mass-spring-damper systems as shown in fig. two vertical and two horizontal. This system would follow the principles of inertia to counterbalance the forces of a tremor. Let’s assume, throughout a tremor the hand will moves in X and Y direction and also sometime it will rotate between X and Y…

Salieri plans on killing Mozart and having the requiem mass performed at his funeral and taking credit for the musical piece. As Mozart begins writing this piece and ventures into other deals in desperation for money he begins drinking heavily, his health worsens and so does his relationship with his wife,…

whose mass are for you to determine. These objects will be labeled with a number or letter. Record the number or letter in…

Inelastic collisions occur when the kinetic energy of an object is not conserved, but converted into other forms of energy, such as heat or potential energy. As such, they still obey the conservation of energy principle that energy cannot be created or destroyed. When two bodies undergo an inelastic collision, their combined initial kinetic energy is not equal to the final kinetic energy of the system. When a tennis ball bounces on the ground, the kinetic energy that the ball possesses just…

The purpose of this lab is to evaluate the relationship between kinetic friction coefficient and static coefficient as well as measure the coefficients of the two friction. Friction is the force that resists relative tangential movement. Its direction is opposite to the relative velocity. Kinetic friction and static friction are two types of friction. Static Friction happens when the two surface in contact remains relatively stationary to each other. It reaches its maximum value before the…

Newton's Second Law: It describes what happens to the body when it is affected by force, as it shows the relationship between the force affecting the body, and the movement acquired by the body. Through the study of Newton's first law, we see that in the absence of an effective force on an object or the existence of a group of balanced forces affecting it, This body will be in a state of stillness or regular movement in the straight line. We continue to study the movement of objects when a force…

Apparatus Retort stand String Meter ruler Table Standard hex nuts (as suspended mass) Stopwatch Labelled Diagram Illustrating setup Method Experiment A: The simple pendulum was assembled using a retort stand, string and steel weight (suspended mass). The suspended mass was attached to the string and the…

Therefore, any problem that can be solved by the work-energy method can, in theory, be solved using the FMA method. There is main advantage of using work and energy method compared to the force-mass-acceleration (FMA) method. 1. Work can be calculated in problem without integration, the change in speed of the particle may be easily obtained with a minimum of computation. 2. Only forces that do work need to be considered which mean a nonworking…

When teaching the skill of sweeping or brushing to novice curlers necessary to always remember the three basic fundamentals. These fundamentals are body weight, brush speed and footwork. Throughout the process of teaching our skill we will continue to highlight these fundamentals ensuring that our teens will remember them and hopefully demonstrate them as they continue to curl. During our teaching of the skill it is important to note that we will always be watching for unsafe practices on the…
