The system shown starts from rest, and each component moves with a constant acceleration. If the relative acceleration of block c with respect to collar B is 60 mm/s^2 upward and the relative acceleration of block D with respect respect to block A is 110mm/s^2 downward, determine (a) the velocity of block c after 3 second. (b) the change in position of block D after 5 seconds.
What will be the length of the specimen after the load is removed? d) The specimen was reloaded until fracture. If the % reduction in area after fracture was 40%, what is the minimum diameter of the specimen at fracture?
You have a 120 Ω quarter bridge 2 wire set up with Sg=2.10 and an unknown lead wire resistance. A 59880Ω calibration resistor is switched in parallel to the gage only and a recording instrument is set to give a -100 mm deflection for this calibrat..
Acceleration was uniform. If it assumed that the acceleration was uniform where the magnitute of the volocity of an airplane was changed from 120mph to 360mph in 6 seconds.
An auto speedometer is graduated in 5 mph increments and has an accuracy rated to be within ±4%. Estimate the uncertainty in indicated speed at 60 mph.
Calculate the change in length of the component - calculate the shear strain in the circular section and the square section
Determine the smallest horizontal force required to lift the 260- crate. The coefficient of static friction at all contacting surfaces is = 0.7. Neglect the mass of the wedge.
What are effects of the annealing process on the density of these dislocations ? Can you give examples for materials?
how long is required for half the ice cube to melt? State clearly all the assumptions you make in formulating your model of this problem.
A jack-screw has a handle 35 inches long and a pitch of 7/32 inches. If a pull of 15 lbs. is required at the end of the handle to lift a 3,000 lbs.
a particle at rest is located at point 325 with units of ft. it is subjected to an acceleration in units of fts2 of a
Coal discharged from a dump truck with an initial velocity (v)= 1.8m/s at 50 degrees falls on conveyor belt B. Determine the required velocity v(B) of the belt if the relative velocity with which the coal hits the belt is to be vertical.
determine the electrical power input to the pump. the density of water is 1kg/l.
