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.

e. A car moving at a speed of 60 km/h is stopped in a distance of 15m. Find (i) average rate of retardation, (ii) time taken and (iii) brake efficiency (assume 9.8 m/s2 as 100 per cent)
Hw.1 1. With a starting velocity of 60 m/s, a tiny projectile is launched vertically downward into a fluid medium. The projectile decelerates by a = (-0.4v) m/s? due to the fluid's drag resistance, where v is measured in m/s. Calculate the projectile's velocity and position 4 s after it is fired. 2. Starting from rest, a particle moving in a straight line has an acceleration of a = (2t - 6) m>s2, where t is in seconds. What is the particle's velocity when t = 6 s, and what is its position when t = 11 s?

Q) Write an expression for the rate of energy expenditure whenshe jogs at the same constant speed up a slope of 4.99 degrees. Assume whatever frictional or drag forces are the same in each case.

Modern roller coasters have vertical loops like the one shown in the figure. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats. Part (a) What is the speed of the roller coaster, in meters per second, at the top of the loop if the radius of curvature there is 15 m and the downward acceleration of the car is 1.3g? Note that g here is the acceleration due to gravity. Part (b) The beginning of this roller coaster is at the top of a high hill. If it started from rest at the top of this hill, how high, in meters, above the top of the loop is this initial starting point? You may assume there is no friction anywhere on the track. Part (c) If it actually starts 3.5 m higher than your answer to the previous part (yet still reaches the top of the loop with the same velocity), how much energy, in joules, did it lose…
A conveyor can accelerate at a constant 0.3 ft/s², decelerate at a constant 0.7 ft/s², and move at a maximum speed of 6 ft/s. What is the fastest time it would take to move a package a distance of 27 ft? The package must begin and end at rest. Sketch the acceleration, velocity, and position as a function of time to communicate (and think through) your answer.
