Question Solved1 Answer F3 45° F1 F2 Given that F1 = 625 N, F2 = 840 N, F3 = 580 N and a = 50° determine the magnitude of the resultant force and its direction, measured counterclockwise from the positive x axis. The magnitude of the resultant force is ( round to one decimal place) : N Direction counterclockwise from positive x-axis is ( round to one decimal place) : degrees

P 6 mm 2. A steel pipe 265mm outer diameter is fabricated from 6mm thick plate by welding along a helix angle of 25º with a plane perpendicular to the axis of the pipe. Knowing that the maximum allowable normal and shearing stresses in the directions respectively normal and tangential to the weld are o=61MPa and t= 37 MPa, determine the magnitude P of the largest axial force that can be applied to the pipe. -Weld 25°

In the figure two identical plastic rods are bent to form a circle of a 10.0 cm radius, one of charge +q and the other of charge −q. The charge is distributed uniformly on both rods. If q = 10 pC, what is the electric field at P, the center of the circle? 2.

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite is first released from a space shuttle, which is in a circular orbit at an altitude of 185 mi, and is then propelled by an upper-stage booster to its final altitude. As the satellite passes through A, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. The booster is again fired at Bto insert the satellite into a geosynchronous orbit. The second firing increases the speed of the satellite by 4850 ft/s. 29.240 mi 185 mi R-3960 mi Determine the speed of the satellite as it approaches B on the elliptic transfer orbit. (You must provide an answer before moving to the next part.) The speed of the satellite as it approaches Bis ft/s.

6. (20 pts) Eurostar is a high speed rail service that connects London to Paris. The distance from London to the English Channel Tunnel is 108.0 km. The English Channel Tunnel is 50.5 km long. The distance from the English Channel Tunnel to Paris is 316.0 km. The train travels at a maximum speed of 300 km/hr except within the English Channel Tunnel, where a 6. (20 pts) Eurostar is a high speed rail service that connects London to Paris. The distance from London to the English Channel Tunnel is 108.0 km. The English Channel Tunnel is 50.5 km long. The distance from the English Channel Tunnel to Paris is 316.0 km. The train travels at a maximum speed of 300 km/hr except within the English Channel Tunnel, where a reduced speed of 160 km/hr is required for safety reasons. a. How long does the journey from London to Paris take? Give you answer in s. b. If the resistance between the train and the track at maximum speed is 120 kN and air resistance adds an additional 20.5 kN (Note: Power = force x velocity), what is the power in horsepower required to power the engine?
