Question 5.
Create a simple balance using a ruler as the balance beam and a pencil as the fulcrum.
Put 2 nickels stacked together on one side of the ruler and a single nickel on the other side so that the ruler is balanced. Does the distance from the fulcrum to the 2 nickels = 1/2 the distance to the single nickel? How would you account for any discrepancy?
The uniform beam has a mass of 46 kg per meter of length. Determine the reactions at the supports.

- John is pushing his daughter Rachel in a wheelbarrow when it is stopped by a brick 8.00 cm high (Fig. P12.15). The handles make an angle of = 15.0 with the ground. Due to the weight of Rachel and the wheelbarrow, a downward force of 400 N is exerted at the center of the wheel, which has a radius of 20.0 cm. (a) What force must John apply along the handles to just start the wheel over the brick? (b) What is the force (magnitude and direction) that the brick exerts on the wheel just as the wheel begins to lift over the brick? In both parts, assume the brick remains fixed and does not slide along the ground. Also assume the force applied by John is directed exactly toward the center of the wheel.arrow_forwardpls help me answer this question, enlightened onesarrow_forwardAn aero engine has Hub diameter of 0.36 and a tip diameter of 0.70, what is the radius of the bladesarrow_forward

- We can model a pine tree in the forest as having a compact canopy at the top of a relatively bare trunk. Wind blowing on the top of the tree exerts a horizontal force, and thus a torque that can topple the tree if there is no opposing torque. Suppose a tree's canopy presents an area of 9.0 m2m2 to the wind centered at a height of 7.0 mm above the ground. (These are reasonable values for forest trees. *Part A If the wind blows at 6.5 m/sm/s, what is the magnitude of the drag force of the wind on the canopy? Assume a drag coefficient of 0.50 and the density of air of 1.2 kg/m3kg/m3.
