Drone Catcher
You are asked to analyze a catcher for a small drone. The catcher arm weighs 22.5 lb and is 8 ft long (you can model it as a slender rod); the net that catches the drone at B has negligible mass. The 3-lb drone has a mass moment of inertia about its own center of mass of 0.01 slug·ft2. Know that after impact the arm swings up to an angle of 30° below the horizontal

Figure Pl 1-12 shows an oil field pump mechanism. The head of the rocker arm is shaped such that the lower end of a flexible cable attached to it will always be directly over the well head regardless of the position of the rocker arm 4. The pump rod, which connects to the pump in the well casing, is connected to the lower end of the cable. The force in the pump rod on the up stroke is 2970 lb...

A large bell is hung from a wooden beam so it can swing back and forth with negligible friction. The center of mass of the bell is 0.55 m below the pivot, the bell has mass 40.0 kg , and the moment of inertia of the bell about an axis at the pivot is 20.0 kg⋅m2 . The clapper is a small, 1.8 kg mass attached to one end of a slender rod that has length L and negligible mass....

What mass for object C will balance the whole system? b. Use the additive nature of moment of inertia and the parallel axis theorem to calculate the total...
What is the angular acceleration of the rod immediately after it is released?
A uniform 7 kg rod with length 10 m has a frictionless pivot at one end. The rod is released from rest at an angle of 23 degrees beneath the horizontal.What is the angular acceleration of the rod immediately after it is released?The moment of inertia of a rod about the center of mass is 1/12 mL2 , where m is the mass of the rod and L is the length of the rod. The moment of inertia of a...

You are a project manager for a manufacturing company. One of the machine parts on the assembly line is a thin, uniform rod that is60.0 cm long and has mass 0.900 kg . Part A:What is the moment of inertia of this rod for an axis at its center, perpendicular to the rod? Part B: One of your engineers has proposed to reduce the moment of inertia by bending the rod at its center into a V-shape, with a 60.0...

The contraption below is made of a slender rod and a circular disk welded to its end. There is a torsional spring with a stiffness k = 1000 N-m/rad attached to the rod at the pin support, O. A projectile is traveling from right to left and strikes the side of the disk and embeds. The pendulum is initially at rest. The rod has a mass of 10 kg and the disk has a mass 20 kg. The projectile has...
