The robot arm is elevating and extending simultaneously. At a given instant, θ = 30°, , = 0.5m, I = 0.4 m/s Compute the radial and transverse forces Fr and Fθ that the arm must exert on the gripped part P, which has a mass of 1.2 kg. Compare with the case of static equilibrium in the same position.
A large tank is used to calibrate the reading from a flow meter. Measurements of the system weight as a function of time are made. Water enters the tank vertically from the flow metering system at a speed of 20 ft/sec through a 1.5 in.
Given that uniform flow is subcritcal and there is a constriction in a rectangular channel, how do you determine what the constricted width would be to force the flow to be critical. Draw this transition on a specific energy curve.
A unform disk of radius R and mass M is mounted on an axle supported on a fixed frictionless bearing. A cable is wrapped around the rim of the wheel and a steady

what is the distiniction b/n point and non point sources of water pollution and thier varation with surface and ground water?
A 250 mm- diameter and 16 m-long timber pile is driven into a sandy soil where ?= 18 kN/m3 and ?' = 34 degree. Estimate the maximum load allowed on the pile with a safety factor of 2.5
Discuss the advantage of maintaining water: cement ratio against the workability of concrete
Determine the water level rise in an unconfined aquifer produced by a seasonal precipitation of four inches. The aquifers porosity is 20 percent and its specific retention is 9 percent.
If the static port of an aircraft became blocked during a climb the vertical speed indicator would: 1.Remain at the previously indicated rate of climb 2.Fall to zero rate of climb indication 3.Indicate a maximum rate of climb 4.Indicate a maximum rat..
The cantilevered wild- flange steel beam is subjected to the concentrated force P at its end. Determine the largest magnitude of this force so that the bending stress developed at A does not exceed 180 MPa.
during construction of the surface layer of asphalt pavement, two samples where taken everyday to measure the asphalt content in the mix to ensure that it is within the specification limits. the target value was set at 5.5 percent with a tolerance..
At what depth will water flow in a 10 m wide rectangular channel, if n=0.01, S=0.0015 and Q=9m^3/s
