Two technicians are discussing using a cone adapter for mounting a wheel. Technician A says it is recommended and prefered to use a collet and pin plates whenever possible instead of a cone. Technician B says it is acceptable to mount most passenger car tires using a "front cone" method (where the cone is inserted into the front face of the wheel). Who is correct? Technician A O Technician B O Both Technician A and Technician B O Neither Technician A nor Technician B​

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
