A wooden bar dimensions are 2.5 in by 5.5 in by 10 ft. its modulus of elasticity is 300,000 psi. What will be the maximum deflection (δmax) of the bar if it is placed on joist orientation on two supports at its two ends and a load of 300lb is placed on its center. (I NEED THE ANSWERS FAST!)

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
