A 3-in.-by-12-in. (S4S) scaffold timber plank is laid flatwise on supports that are 8 ft apart. Calculate the allowable uniformly distributed load that can be carried by the plank.
The allowable bending stress is 1600 psi and the allowable shear stress is 100 psi. Neglect the weight of the plank.
Consider a two- dimensional, straight triangular fin of Length L= 50mm and base thickness t= 20mm. The thermal conductivity of the fin is k= 25 W/mK. The base temperature is T_b= 50 degrees Celsius, and the fin is exposed to convection conditions cha..
Name two purposes and advantages of jigs and fixtures that are used as work holding devices
determine the speed of the cam and use the motion equations and a spreadsheet to plot a displacement diagram of the
If it is supported by the cable AB and hinge at C, determine the tension in the cable when the truck begins to accelerate at 5 m> s2. Also, what are the horizontal and vertical components of reaction at the hinge C?
Determine the failure load for the crack-free jaw. For the crack-free jaw, what would be the factor of safety based on stress/load. Which failure occurs first- the crack or the failure in the pins
Design the beam (that is, determine the material, cross-sectional dimensions, and the length of the beam) such that the stress induced in the beam should not exceed the yield stress of the material under an acceleration of 0.2 g at the top of the ..
How much energy will be required to evaporate the droplet if the dry ambient air temperature is 27°C, while the droplet-heater temperature remains at 37°C?
A pressure gauge reads in Tuscaloosa alababama 16 psi. Can this pressure be a vacuumed pressure? Why or why not? If you think it can convert it to absolute pressure. If you think it cant assume that it is a gauge pressure and convert to absolute pres..
A 8-cm diameter horizontal jet of water strikes a flat plate at a velocity of 30 m/s. Calculate the force exerted by the water stream on the plate.
A copper plate 2 mm thick is heated up to 400oC and quenched into water at 30 C - Find the time required for the plate to reach the temperature of 50 C.
at the beginning of the compression process of an air-standard otto cycle p1 14.7 lbin2 and t1 530degr. the maximum
A reciprocating compressor has been selected to compress 0.085 m3/s of 25oC methane gas from 100 to 6200 kPa. Assuming that the heat capacity remains constant at 2433 J/(kg?K) over the temperature range of compression and that the ratio of C p/C v ..
