A horizontal het of water at 5 degrees celsius strikes a block and is deflected upward 30 degrees. The mass flow rate of the water is 1.75 kg/s. The mass of the block is 1.30 kg. The jet has a cross sectional area of 10 cm^2. The coefficient of static friction is 0.150. The block is being pushed toward the left at 0.75 m/s. What is the net force of the water on the block?
A composite beam is made by attaching the timber and steel portions with bolts of 14-mm diameter spaced logitudinally every 200 mm. The modulous of elasticity is 10 GPa for the wood and 180 GPa for the steel.
Both streams have a ?nal speed V = 18 ft/s. Disregarding gravitational e?ects, determine the x- and z-components of the force required to hold the splitter plate in place against the water force.
velocities in a 200-mm-diameter circular conduit, measured at radii of 0,36,64, and 87 mm were 7.0, 6.8, 6.1, and 5.0 m/s, respectively. Find the approximate values (graphically) of the volume flow rate and the mean velocity.
Which software do we use to calculate force and moment, and draw shear and moment diagram? I really need this software to design my structural project. Please helps me... thank you so much
Christian is picking out ties for a business trip. Anastasia knows from experience that Christian has a 50% chance of picking a grey tie. Find the probability Christian won't pick out a grey tie until the 3rd or 4th tie.

A river with 400 ppm of salts (a conservative substance) and an upstream flow of 25 m^3/s receives an agricultural discharge of 5.0 m^3/s carrying 2000 mg/L of salts.
A marble is drawn at random from a box containing 10 red, 30 white, 20 blue, and 15 orange marbles. Find the probability that is: (a) orange or red (b) not red or blue (c) not blue (d) white (e) red, white, or blue
What criteria are used in the selection of personnel for the demonstration of maintenance tasks? Define the criteria for the selection of test and support equipment.
The end of a 0.75-in-diameter rod is fixed to an immovable plate. The length of the rod is 18.0 in. A 50-lb weight is attached to a 16.0-in lever at the end of the Rod so that the weight is hanging perpendicular to the longitudinal axis of the rod..
A simple way to model air pollution over a city is with a box model that assumes complete mixing and limited capability for the pollution to disperse horizontally or vertically except in the direction of the prevailing winds
A smooth hump is placed in the bottom of the channel. What would be the depth of flow over a 3 ft high jump. How high can the hump be made without backing flow up What would be the depth of flow over and just upstream of a 6 ft high jump
