A camera is packed in a box and surrounded by packing material. The box is dropped vertically onto a horizontal surface. The vertical velocity of the box at the time that it hits the surface is v= 5m/s. After impact the camera experiences an acceleration of a = -kx, where k is a constant and x is the compression of the packing material. If the packing material experiences a maximum compression of 30 mm, determine the maximum acceleration of the camera.
Compute the maximum service (unfactored) concentrated live load that can be applied at 1ft from the free end of the cantilever. Use load and strength -reduction factors from ACI Code Sections 9.2 and 9.3. Also check As,min.
Determine the factors of safety against sliding and against overturning, and also the soil pressure at the heel and toe. Assume hydrostatic uplift varies uniformly from full hydrostatic head at the heel of the dam to zero at the toe. consider 1m l..
A delivery company accepts only rectangular boxes the sum of whose length and girth (perimeter of a cross section) are equal to 108cm. Find the dimensions of an acceptable box of a largest area.
A constant power of 1.5 hp is supplied to the motor while it operates with an efficiency of ε = 0.8. Determine the velocity of the 200-lb crate in 15 seconds, starting from rest. Neglect friction.
Motor M draws in the cable with an acceleration of 4 , measured relative to the 220 mine car. Determine the acceleration of the car. Neglect the mass of the pulleys.
The IIT components of ownership cost based on average annual value are: Tax-3%, Insurance -4%, and Interest-7%. a) What is the average annual value?
Plot the variation with depth (z) of the at-rest lateral earth pressure behind the wall, and determine the magnitude and location of the at-rest lateral earth force per unit length of wall.
Also, at the failure cross sections the diameters are found to be 0.731 in., 0.645 in., and 0.587 in., respectively. Determine the percent elongation and percent reduction in area of each specimen.
A gas is compressed at a constant pressure of 0.800 atm from 9.00L tp 2.00L. in the process, 400J of energy leave the gas by heat. (a) What is the work done on the gas? (b) What is the change in it internal energy?
A 1.50 L buffer solution is 0.250 M in HF and 0.250 M in NaF. Calculate the pH of the solution after the addition of 0.0500 moles of solid NaOH. Assume no volume change upon the addition of base. The Ka for HF is 3.5 x 10 -4 .
You may assume that the total pressure at the downstream station is uniform across the tunnel and given by the value at the wall. Neglecting gravitational effects.
