The table represents the function f(x). a 2-column table with 7 rows. the first column is labeled x with entries negative 3, negative 2, negative 1, 0, 1, 2, 3. the second column is labeled f of x with entries negative 9, negative 6, negative 3, 0, 3, 6, 9. what is f(3)? –9 –1 1 9

Around steel bar, made from material with a yield stress of 750mpa, is loaded so that it has stresses co locations of maximum normal stress and maximum shear stress. use maximum shear stress and maximum distortion energy theories to calculate the safety factors for initial yielding failures.
