Answer #1

To support the wheelbarrow, moment is balanced (Torque) load = 130kg F=? prvot (wheel) Torque about a> -> 130x9.81* d = Fxlo1

    John is pushing his daughter Rachel in a wheelbarrow when it is stopped by a brick 8.00 cm high (see the figure below). The handles make an angle of 0 = 18.0° with the ground. Due to the weight of Rachel and the wheelbarrow, a downward force of 379 N is exerted at the center of the wheel, which has a radius of 19.0 cm. Assume the brick remains fixed and does not slide along the ground. Also assume the...

    A person pushing a horizontal, uniformly loaded, 21.95 kg wheelbarrow of length L is attempting to get it over a step of height h=0.510R, where R is the wheel's radius. The center of gravity of the wheelbarrow is in the center of the wheelbarrow. What is the horizontal component Px of the minimum force P→ necessary to push the wheelbarrow over the step? The gravitational acceleration is g=9.81 m/s2. Px= 1 OL

    A woman rides a bicycle down a hill with a 15% slope (rise/run). The combined mass of the bicycle plus woman is 50 kg. She is riding into a 20-km-per hour wind. The only forces acting on the woman are drag force and weight. If the woman and bicycle together have a projected area of 1.0 m2, and the coefficient of drag is 1.1, how fast is the bicycle going relative to the ground? The density of air is 1.23...
