An object whose mass is 2 kg is accelerated from a velocity of 200 m/s to a final velocity of 605 m/s by the action of a resultant force. Determine the work done by the resultant force, in kJ, if there are no other interactions between the object and its surroundings.
A concentrated downward force of 2000 lb. is located 6' from the left support, and a uniformly distributed load of 200 lbs./lin. ft. begins 6' to the right end of the member. What force must be applied at each connection to maintain equilibrium?
During that same hour, 20 departing aircraft uniformly arrive at the runway within a 20-minute period. Assume no other departing aircraft arrive at the runway during the hour.
There are 3 forces acting on the ring. using the non vector approach, determine the resultant force of only the 150 Ib and 100 Ib forces. Also calculate the angle between the resultant force and the positive x axis.
Determine the vertical displacement of B using Castigliano's 2" Theorem Determine the reactions For the beam shown using the FOnce method
A projectile is fired with an initial velocity of 800 ft/s at a target B located 2000 feet above the gun A and at a horizontal distance of 12,000 feet. Neglecting air resistance, determine the value of the angle at which the projectile is fired.
Compute the final velocities υ1 and υ2after collision of the two cylinders which slide on the smooth horizontal shaft. The coefficient of restitution is e = 0.6.
What are some alternative ways of insulating the walls of a wood light frame building to R-values beyond the range normally possible with ordinary 2 4 (38 89 mm) studs?
A cylinder of rock with a Poisson's ratio of 0.422 has ano-load length equal to 17.6 cm and a no-load diameter of 6.20cm. Under an axial compressive load the axial strain is foundto be -3.44 mm/m.
For arectangular section (b(width) x h(thickness) that is subjected to aforce P that is applied at an eccentricity (e) measured from thecenter of area of the rectangle in the h(thickness)direction
What is the difference between the component pressure and the partial pressure
Two identical pool balls of 57.15 mm diameter may move freely on a pool table. Ball B is at rest and ball A has an initial velocity v=v0i. (a) knowing that b=50 mm and e=0.7, determine the velocity of each ball after impact.
Knowing that the magnitude of P is 35 N, determine by trigonometry (a) the required angle a if the resultant R of the two forces applied to the support is to be horizontal, (b) the corresponding magnitude of R.
