Answer: A knuckle joint is used to connect the two rods which are under the tensile load, when there is requirement of small amount of flexibility or angular moment is necessary. There is always axial or linear line of action of load.
The knuckle joint assembly consist of following major components :
2.Double eye or fork.
At one end of the rod the single eye is formed and double eye is formed at the other end of the rod.Both, single and double eye are connected by a pin inserted through eye.The pin has a head at one end and at other end there is a taper pin or split pin. For gripping purpose the ends of the rod are of octagonal forms.Now, when the two eyes are pulled apart, the pin holds them together .The solid rod portion of the joint in this case is much stronger than the portion through which the pin passes.p
Answer: Typically, there are 2 reasons:1. To check for an increase/decrease in swelling2. To check range of motion (using a goniometer)Usualy, this is done after surgery or injury to the joint. Measurements are used to determine how well you are healing as well as how you are progressing in treatment (e.g. physical therapy).
Answer: Yes, they are replaceable.Always disconnect battery terminals Your first responsibility prior to starting the installation process is to disconnect the terminals from the battery. Furthermore, make sure to let the car sit for at least one hour so that any battery backups from the SRS system have completely drained.Never probe the airbag with your meter WARNING! Never use the probs on your meter to directly test the terminals or connectors on any airbag. The airbag requires only 2 - 3 ohms for deployment and touching the airbag terminals with your meter may provide enough current to activate the airbag. This warning applies to all airbag types, including but not limited to side airbags, roof airbags, knee airbags, foot airbags, seat airbags, etc.
Answer: It all depends which lead is connected to the common power supply, Emitter, base or collector. For most amplification needs using NPN transistors, common emitter is used. Other applications are used for current control and regulation circuits.
