1.A tugboat tows a ship at a constant velocity. The tow harness consists of a single tow cable attached to the tugboat at point A that splits at point B and attaches to the ship at points C and D. The two rope segments BC and BD angle away from the center of the ship at angles of = 27.0 and = 21.0, respectively. The tugboat pulls with a force of 4700 . What are the tensions and in the rope segments BC and BD?
2.Water under a gage pressure of 350kPa flows with a velocity of 5 m/s through a right-angled bend that has a uniform diameter of 250 mm. The bend lies in a horizontal plane, and water enters from the west and leaves toward the north. Assuming no drop in pressure, what is the magnitude and direction of the resultant force acting on the bend?
the hypothetical velocity distribution in a horizontal rectangular open channel is v0.3y msnbspwhere v is the velocity
Compute the following assuming HL93 loading is the live load.Draw loading diagrams so I can see the placement of your loads forALL cases considered.
The effective angle of friction (phi) was found to be 26 degrees for a normally consolidated soil. If the soil is tested in consolidated drained triaxial test under sigma3 = 60 kPa, what would be the failure deviatoric stress sigma1-sigma3 stress
An airport corridor is 30 ft wide. given a peak demand of 300 pedestrians per minute and an average walk speed of 3 ft/s, estimate the LOS at the corridor
A 4x4 carries an axial compressive force caused by dead, love, and roof live loads. Lumber is No. 1 Douglas Fir-Larch. Cm = 1.0 , Ct = 1.0, Ci = 1.0. The unbraced length of the member is 12 ft.
shown in the figure are a mast and a portion of the rigging of a schooner. members cd and ef lie in the same plane.
An observer has determined that the time headways between successive vehicles on a section of highway are exponentially distributed and that 60% of the headways between vehicles are 15 seconds or greater.
A girder that carries a uniformly distributed dead load of 1.7 K/ft plus its self-weight and three concentrated live loads of 15 kips at quarter points of that 36 ft span is to be sized.
A column of dimensions 200 X 300 mm has an effective length of 3m. It is reinforced with 6 HYSD bars of 20mm diameter. Determine the safe load the column can carry using working method of design. Using M20 Concrete.
An ocean outfall diffuser that discharges treated wastewater into the Pacific Ocean is 500m from a public beach. The wastewater contains 105 coliform bacteria per milliliter. The wastewater discharge flow rate is 0.3 m3/s.
each wire has a tension of 1kN and is inclined at 45 degree to the vertical. calculate the increase in vertical stress at a depth 1 m below the surface and the amount of elastic settlement below the axis of the pole if E = 40 Mpa and v=0.45
The elevtion of M is 875 . a transit was set at point M and a leveling rod was held vertically at point N. the horizontal cross line of the telescope was inclined so the reading of the horizontal cross line
