Question 4 [25 marks] An electric motor drives a coaxial rotor through a single-plate clutch which has two pairs of driving surfaces each 300 mm external and 175 mm internal diameter. The variation of normal pressure with radius is given by a + b/r Pa and the maximum pressure is 150 kPa. The spring force on the system is 500 N. The mass of the motor armature and shaft is 750 kg and its radius of gyration is 240 mm;...

summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
