1.Two people are pulling a boat through the water . Each exerts a force of 600 N directed at a ?= 20.0° anglerelative to the forward motion of the boat. If the boat moves withconstant velocity, find the resistive force exerted by the water on the boat.
2.Write a brief paragraph summarizing the following Habitat Simulation Method used to analyze environmental flow requirements.
i. Physical habitat simulation (PHABSIM)
3.The acrylic plastic rod is 200mm long and 15mm in diameter. If an axial load of 300N is applied to it, determine the change in its length and the change in its diameter. Ep = 2.70 GPa, Vp = 0.4.
For almost all new coal plants, Clean Air Act emission standards limit emissions of sulfur dioxide (SO2) to 260 grams per million kJ of heat input (fuel value). They also restrict particulate emissions to 13 g/106 kJ.
1.102 Determine the intensity w of the maximum distributed load that can be supported by the hanger assembly so that an allowable shear stress of τallow = 13.5 ksi is not exceeded in the 0.40-in.-diameter bolts at A and B
To be sure that the part does not fail, we plan to ensure that the maximum applied stress is only one third of the tensile strength. We use a non-destructive test that will detect any internal flaws greater than 1.25 mm long.
A piston cylinder contains 0.8kg of steam (water vapor) at 300 deg C and 1MPa absolute. The steam is cooled at constant pressure until half of the mass condenses.
Submit your cost analysis for the materials, along with a scaled drawing of the truss, identifying on the drawing the tensile and compressive force in each member. Also include your calculations of the complete force analysis.
Find the change in volume of 16.15 lb of water at ordinary atmospheric pressure for three conditions: Calculate each condition and note the trend.
A 100 ft cut steel tape was used to measure between two property markers. The rear surveyor held 93 ft, while the head surveyor cut .67ft. What was the distance between the markers
a pre-engineering base line was run down a very steep hill.rather than measure horizontaily down hill with steel tape
The symmetrical scissors truss shown below is supported atpoint A and D. The support at D is a rocker bearing and does notproduce a horizontal reaction. A, B, C, D, E & F are pinjoints.
why are the pressure for those p2/p1 different than whats given for question 3.2.3 in Fluid mechanices with engineering application 10ed
The coefficients of static and kinetic friction are 0.3 and 0.2, respectively, between each of the plates and between plate A and the ground. Determine the acceleration of each plate.
The velocity of propagation, c of surface waves is assumed to depend on the water depth, y, the water density, and the acceleration due to gravity, g. Express these variables as a dimensionless group.
