Below is a stress strain graph up to the point of fracture for a rod of cast iron The rod of a cast iron has a cross sectional area 1.5x10-4 calculate the force applied to the rod at the point of fracture

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
