but by interference. The two parts of the clutch are designed such that one will push the other‚ causing both to rotate at the same speed and will never slip. Dog clutches are used where slip is undesirable and/or the clutch is not used to control torque. Without slippage‚ dog clutches are not affected by wear in the same way that

Controlled Assessment – Helicopters You need to research information (using the internet) that includes answers for the following questions: 1. How the turning rotor makes a helicopter move upwards 2. How the rotor is made to turn in a helicopter and in an autogyro 3. How autorotation is used to help land a helicopter safely if the engine fails 4. Why a helicopter; falling during autorotation‚ could reach a terminal speed without the pilot changing any controls 5. The effect of the weight of

application. The immediate objective of this research project is to measure the mechanics of laryngoscopy‚ so that an advanced training mannequin can be developed. This summer an instrumented laryngoscope has been developed which uses a 6-axis force/torque sensor and a magnetic position/orientation sensor to quantify the interactions between the laryngoscope and the patient. Experienced physicians as well as residents in training have used this device on an existing mannequin‚ and the force and motion
