To use the equations of equilibrium to analyze a system containing a wedge and to determine the necessary applied force to introduce motion into the system. The crate shown is held against wedge B by a spring. The spring is 96.0% of its original uncompressed length l= 3.00 m, and the spring constant is given as k = 1750 N/m. The coefficient of static friction at all contacting surfaces is ls = 0.150. The mass of the crate is m = 23.0 kg . The angle is 0 = 13.0°. Neglect the mass of the wedge. Assume the crate only moves in the y direction and that wedge A cannot move. (Figure 1) Figure 1 of 1 В
5. A nail and a hammer are modeled by a linear spring and an incident mass according to the figure. (The nail is supposed to be driven into a piece of very hard wood and cannot move into the wood for the velocity given to the hammer). m EA k The hammer has an initial velocity vo = 5m/s and a mass m= 0.7 kg. The nail is made of steel E = 210 GPa and the cross section is square A = 2 x 2 mm, with a length L = 0.1 m. Determine the maximum force Fmax reached in the contact between hammer and nail and the duration At of the force pulse.
