A vehicle is approaching a two-lane highway at a spee designed for that highway. It is a 3-degree curve (D) of le ft.

(a) What is the radius of curvature (R) and central angle of curve delta
(b) There's no superelevation, and the coefficient way at a speed of 100 mph. A horizontal curve is ve x(D) of length 1,500 ft. The lane width is 12 and central angle of the curve (4) Ticient of side friction is 0.11. Can this vehicle navigate the curve safely without slowing down? And why

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.

On a average work day more than work place firs are reorted

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented
