In the current state, the same set of material particles forms a tetrahedron of some other shape, and the forces acting on all faces are in the direction of x1 , with the forces on faces a1 , a2 , a3 being of magnitudes 4, 5, 6, respectively. calculate the force on face a. calculate the nominal stress tensor.

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
