Concept explainers

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

A weight of 450 N rests upon a vertical spring whose scale is 140 N/mm. The spring is then pressed down 180mm farther by an added pressure of 4 kN. If this added pressure is then released suddenly, what will be the velocity of the 450 N weight 1.50m above the depressed position.
A projectile, initially at the origin, moves along a straight-line path through a fluid medium such that its velocity is v=1800(1-e^-0.3t)mm/s where t is in seconds. Determine the displacement of the projectile during the first 3 s.
The ship was traveling at 2.5 m/s toward the reef when a mechanical failurecaused the rudder to jam in the straight-ahead position. At that point in time, the shipwas 900 m from the reef. The wind was blowing directly toward the reef and exertinga constant force of 9.00 x 103 N on the boat in a direction toward the reef. The massof the ship and its cargo was 5.50 x 10 kg. During the preparation for the trial, thecaptain claims that without control of the direction of travel, the only choice he hadwas to put the engines in reverse at maximum power, such that the total force exertedby the frictional drag force of the water on the propeller was 1.25 x 10-N in a directionaway from the reef. From this information, construct a convincing argument thatnothing the captain could do in this situation could have prevented the sh fromstriking the reef.
Ball B is being suspended by a 1000mm long elastic cord from a wooden ceiling. The ball’s mass is said to be at 1,500 grams. If this cord is suddenly stretched downward 0.25m and the ball is released from rest, determine the distance (in mm) that the cord stretches after the ball rebounds from the wooden ceiling. Let’s say that the ball makes a central impact with the ceiling. Use the provided data below:
