conditions are satisfied in static systems all forces and torques sum to zero. In problems where the first and second conditions of equilibrium are satisfied‚ the best strategy is to create FBD’s for both the first and second conditions‚ derive equations based on these FBD’s and then see what useful information may be gleaned from these equations. When applying the second condition we are free to choose any axis about which to compute torques. It is best to choose an axis that eliminates one or more

the front wheels. In the present day automobiles‚ power steering assist has become a standard feature. A hydraulic power steering uses hydraulic pressure supplied by an engine-driven pump. Power steering amplifies and supplements the driver-applied torque at the steering wheel so that steering effort is reduced. The recent introduction of electric power steering in production vehicles eliminates the need for the hydraulic pump. Electric power steering is more efficient than conventional power steering

Different models of mobile phones have evolved and continue to develop into new series of high-end handsets. Mobile companies are thinking of ways to cater the needs of every consumer as well as to compete in the mobile communications industry. The trend nowadays in the mobile industry is Smartphones which are mobile phones with advanced technological features. The first smartphones combined the functions of a personal digital assistant (PDA) with a mobile phone and later models added the functionality

When Steinbeck regains consciousness he realized the suspect had located and stole $1500 in US currency. The Riversend CSI personnel unit responded to the crime scene location and gathered evidence. Upon gathering evidence‚ two samples of blood were obtained at the scene. One sample was found located on a bloody wrench used to assault Steinbeck (Photo‚20).The second

But balance is affected by gravity. In order for balance to occur the net force needs to be zero as well as the torque force. In ballet gravity pulls down the dancer and the floor pushes up its own equal force to maintain balance (Gollin). “…An object is [balanced] if its center of [gravity] lies above its base” (Zitzewitz 825). A dancer needs to find his or her center

shafts. We tend to see lot of applications of the couplings mainly in the automobiles‚ for example the drive shaft which connects the engine and the rear axle in a bus or any automobile is connected by means of a universal joint. In order to transmit torque between two shafts that either tend to lie in the same line or slightly misaligned‚ a coupling is used. Based on the area of applications there are various types of coupling available. But they are generally categorised in the following varieties

Strong verbal encouragement was provided from the last submaximal trials until the end of the session for each contraction. After recording the torque of the first limb (randomly chosen)‚ an identical experimental protocol was strictly applied to the second limb. For every condition‚ five repetitions were measured for knee extensors and flexors: concentric at 60°/s‚ concentric at 30°/s‚ eccentric

To experimentally conclude whether the average radius of the friction plate is proportional to the frictional torque.
