If F_1=470N and theta=26 degrees, determine the magnitude of the resultant force of the three forces acting on ring A.
Determine the direction of the resultant force measured counterclockwise from the positive x-axis.
When a particle falls through the air, its initial acceleration a=g diminishes until it is zero, and thereafter it falls at a constant or terminal velocity v_f . If this variation of the acceleration can be expressed as a=(g/v^2_f)(v^2_f-v^2)
For a cantilever beam 20 ft long under a uniformly distributed load of 500 pounds/foot, calculate the deflection v and the slope dv/dx as a function of x by integrating differential equations.
street nam sizes on the signs at a certain location can be discerned by a person with 20/40 vision from a distance of 300 ft. how much larger should the street names be in order to be legible to a person with 20/50 vision from a distnace of 450 ..
Comparison between steel structures and aluminium structures, To make a comparison between Eurocode 3 and Eurocode 9 outlining the main differences
A river upstream of a brdige corssing is 3 meters deep and has an average velocity of 3 m/s. The bridge piers cause a constriction in the width of the flow by 12%.
The receiver's velocity is constant at 10 yd/sec, and he catches passes when the ball is 6 ft. above the ground. If the quarterback desires the receiver to catch the ball 2.5 sec. after the launch instant, determine the initial speed v0 and angle,..
Identical bricks 0.1m wide, and weighting 2kg are placed on a plate (assume the plate has neligible weight). Calculate the total weight (and force F required to balance the plate). How far from x=0 should F be placed so that the plate will not tip..
A $78,000 invtestment in machinery is proposed. It is anticipated that this investment will cause a reduction in net annual operating disbursements fo $16,300 a year for 12 years. The investement will be depreciated for income tax purposes
calculate the moment of inertia for the Milkyway. Assume it to be a disk.
The roadway follows the equation (x^2/(60m)^2) + (y^2/ (40m) ^2) = 1 where x and y are in meters. Find the maximum acceleration experienced by the cars. Hint: begin by making a sketch of the ellipse.
Ammonia vapor flows through a valve. It enters the valve at a pressure of 8 bar and a temperature of 120C and after going through a throttling process it exits at a pressure of 3.5 bar.
Determine the projected component of the force fac along the axis of strut ao. Express the result as a cartesian vector.
