A floor is to be supported on hardwood timber joists that are spaced at 0.5m centres and span 5.0m. The joists support flooring 20mm thick and an applied live load of 2kN/m2
Design a typical joist 50mm wide
Given data;
Density of timber = 800kg/m3
Bending Stress limit = 11.0 MPa
Shear Stress Limit = 1.0MPa
Youngs Modulus = 10.5 x 10^3 MPa
The 90-lb force is required to drag the 200-lb crate 60 ft up the rough inclined plane at constant velocity. If the force is removed when the crate reaches point B, and the crate is then released from rest
Determine the the max weight of the block that the system does not fail if the max tension that can be developed in cable DB is 100N and the max compression that can be developed in tower CD is 100N.
The hypothetical velocity distribution in a horizontal, rectangular open channel is V=0.3y (m/s), where V is the velocity at a distance y (m) from the bottom of the channel. If the vertical depth of flow is 2 m and the width of the channel is 4 m,..
Steam at 10 MPA, 600 C, enters a well insulated turbine operating at steady state and exits at 0.1 bar and a quality of 92%. The volumetric flow rate at the inlet is 0.36 m^3/s. Assuming the kinetic and potential energy effects to be negligible, dete..
How would you structure a portion of an Aviation Safety program for a commercial airline or government agency. Briefly describe one or two safety problems and why it is a serious safety problem.
a. Determine the shear and moment diagram. b. Calculate the maximum normal stress on the top of the beam, on the bottom of the beam and indicate in terms of x its location.
According to the photon energy formula, tripling the frequencyof the radiation from a monochromatic source will change the energycontent of the individually radiated photons by what factor
calculate the magnitude and direction of the horizontal force exerted on the contraction (not on the water). Assume that there is no loss of energy in the contraction. Use the gamma of water is equal to 1000 kg/m^3
A 200 foot long, 2.5 feet in diameter, straight, corrugated metal storm drain pipe, is used to drain a parking lot. The elevation difference between the pipe ends is 8 feet. What velocity would be expected
Create 3 user defined functions to use in the script. function "flip" simulates the flip of one coin with the state "s" of the random number generator as the input argument, and the nes state "s" and the result of the flip (0 for a tail and 1 for ..
Determine the side slopes (i.e. 1:3, etc.) of a suppressed (n=0) trapezoidal sharp crested weir with width B and upstream head H so that the discharge through it is the same as that through a rectangular sharp crested weir
A field party is capable of making taping observations with a standard deviation of +,-0.003m per 30m taped length. What standard deviation would be expected in a distance of 120m taped by this party
