A punch press, used for stamping sheet metal, has a punching capacity of 50 kN. The section ofthe frame is as shown in Fig. Find the resultant stress at the inner and outer fibre of the section.
communication satellites are placed in a geosynchronous orbitthat is in a circular orbit such that they complete one
For the hinged gate shown in Fig. 4.61, determine the magnitude, direction, and location of the force of the fluid acting on it. Complete a free-body diagram and determine the force that the gate exerts on the stop.
Using Dimensional Analysis, derive an expression for the drag coefficient of a high speed flow. At high speeds, you may assume the total drag depends on the fluid density p, average velocity U, Length scale of the object L, but does not depend on the..
The moment of inertia of three rotors A,B and C are respectively 0.3, 0.6 and 0.18 kg-m2 . The distance between A and B is 1.5 m and B and C is 1 m. The shaft is 70 mm in diameter and the modulus of rigidity for the shaft material is 84 x 109 N/m..

INSTRUCTIONS: Use Sheet Metal and Weldments to create the assembly file shown in FIGURE
in order to help design a water channel that will be constructed on the moon an experiment is being conducted on earth.
a rigid 1.0 m3 tank contains water initially at 120oc with 50 liquid and 50 vapor by volume. a pressure-relief valve on
A jet plane cruises at a speed of 980 km/hr. air enters the turbojet engines at 0.73 bar, 230 k. the pressure ratio across the compressor is 10 and the turbine inlet temperature is 1650 k.
Estimate the total time required for a signal verification. What are the advantages and disadvantages of this method in comparison to having the user punch in an identification code alone or provide the signature without the identification code?
Compute the pressure at the base of the tank? Show your work. Compute the force on one of the walls exerted by the air, gasoline and water. Show your work.
For the composite bar of Prob. 2.111, determine the residual stresses in the tempered-steel bars if P is gradually increased from zero to 98 kips and then decreased back to zero.
