1.Briefly Explain Griffith's fracture Model and how it can be related to the Charpy test.
2.Hydrostatic force
A dam is inclined at an angle of 30o from thevertical and has the shape of an isosceles trapezoid 100 ft wide atthe top and 50 feet wide at the bottom and with a slant height of70 ft. Find the hydrostatic force on the dam when it is full ofwater?
