Plot the data as engineering stress versus engineering strain. (b) compute the modulus of elasticity. (c) determine the yield strength at a strain offset of 0.002. (d) determine the tensile strength of this alloy. (e) what is the approximate ductility, in percent elongation

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
