As shown in the figure below, a uniform beam is supported by a cable at one end and the force of friction at the other end. The cable makes an angle of \( \theta=30^{\circ} \), the length of the beam is \( L=4.00 \mathrm{~m} \), the coefficient of static friction between the wall and the beam is \( \mu_{s}=0.600 \), and the weight of the beam is represented by \( w \). Determine the minimum distance \( x \) from point \( A \) at which an additional weight \( 2 w \) (twice the weight of the rod) can be hung without causing the rod to slip at point \( A \). \[ x=m \] the figure below, the CG of the pole held by the pole vaulter is \( 1.79 \mathrm{~m} \) from the left hand, and the hands are \( 0.733 \mathrm{~m} \) apart. ssume the vaulting pole has a mass of \( 4.72 \mathrm{~kg} \). 1) Calculate the force (in \( N \) ) exerted by his right hand. (Enter the magnitude.) N 3) Calculate the force (in \( N \) ) exerted by his left hand. (Enter the magnitude.) N \( \Rightarrow \) If each hand supports half the weight of the pole in the figure below, show that the second condition for equilibrium (net \( \tau=0 \) ) is satisfied for a pivot other than the one located at the center of gravity of the pole. Explicitly show how you follow the steps in the Problem-Solving Strategy for static equilibrium. (Submit a file with a maximum size of 1 MB.)
