Explanation Given: Mass of bullet = m Mass of wooden disk = M Velocity of bullet = v 0 Height = h = R/2 Concept used: Impulse momentum Principle Calculation: Condition after penetration of bullet into disk. According to impulse and momentum, Y = component (vertical) = 0 + N Δ T − w Δ T = 0 ( N = W ) 0 = 0 x = component (horizontal) = m v 0 + f Δ T = M v 1 ¯ m v 0 − μ w Δ T = M v 1 ¯ ------------( f = μ w ) at Δ T = 0 ( m v 0 ) = ( R − h ) = ( I ω 1 ) m To determine (b) The disk’s linear velocity after its motion has become uniform.

A crate weighs 530 lb and is hung by three ropes attached to a steel ring at A such that the top surface is parallel to the xy plane. Point A is located at a height of h = 42 in above the top of the crate directly over the geometric center of the top surface. Use the dimensions given in the table below to determine the tension in each of the three ropes. 2013 Michael Swanbom cc00 BY NC SA ↑ Z C b B У a D Values for dimensions on the figure are given in the following table. Note the figure may not be to scale. Variable Value a 30 in b 43 in 4.5 in The tension in rope AB is 383 x lb The tension in rope AC is 156 x lb The tension in rope AD is 156 x lb

A block of mass m hangs from the end of bar AB that is 7.2 meters long and connected to the wall in the xz plane. The bar is supported at A by a ball joint such that it carries only a compressive force along its axis. The bar is supported at end B by cables BD and BC that connect to the xz plane at points C and D respectively with coordinates given in the figure. Cable BD is elastic and can be modeled as a linear spring with a spring constant k = 400 N/m and unstretched length of 6.34 meters. Determine the mass m, the compressive force in beam AB and the tension force in cable BC.
