A projectile is launched with an initial speed of 200m/s at anangle of 60degree with respect to the horizontal. compute the distance "R" as measured up the incline.
Basically the projectile is launched on incline, the angle is60degee with respect to the horizontal, so its 40degree if taken from the incline.
solve the problem
A steel bar serving as a vertical hanger to support heavy machinery in a factory is attached to a support by the bolted connection. The main part of the hanger has a rectangular cross section with width b1 = 1.5 in. and thickness t = 0.5 in.
what was involved in the first far-reaching, comprehensive study of Earth's oceans?
The maximum wind pressure on the traffic sign is 200 kg/m2. The maximum allowable shear stress is 350 kg/cm2. Design the traffic pole (only vertical element) against torsion knowing that angle of twist at the base should not exceed 6°.
A piston-cylinder device contains helium gas initially at 150 kPa, 20 degrees C, and 0.5 m^3. The helium is now compressed in a polytropic process (PV^n = constant) to 400 kPa and 140 degrees C.
Collar A is dropped 30 inches onto collar B, which is resting on a spring of constant k= 4 lb/in. Assuming perfectly plastic impact (coefficient of restitution e=0), determine the maximum deflection of collar B.
When using singularity functions, if I have a reactionary moment at a cantilever connection, do I use the right hand rule to solve the moment and determine it's direction through the reactions
An intake conduit from a well field used to pump ground water is being designed for a town with a population of 23,000 people. Six years ago the population was 21,500 people. a) assuming deometric growth, calculate the population in 50 years
The foof of the culvert will be located 3 m below ground surface. Currently the groundwater level is at ground surface. But, after installation of the culvert, the groundwater level is expected to drop 2 m below ground surface.
Consider the air over a city to be a box 100km on a side that reaches up to an altitude of 1.0 km. The air is blowing into the box along one of its sides with a speed of 4 m/s.
The break up of a liquid jet into droplets of diameter d depends on the jet diameter D, the jet velocity V, viscosity Mu, density rho,and surface tension sigma.
A waste heat source is available at 400°C. A heat engine operates using heat from this source. It rejects heat to the surroundings at 38°C. The power from the engine runs an air conditioner to keep the air inside a building at 25°C
