A woman is pushing a load in a wheelbarrow, as in
(Figure 1). The combined mass of the wheelbarrow and the load is 130kg, with a center of gravity at d = 0.35m behind the axle. The woman supports the wheelbarrow at the handles, 1.1 m behind the axle..

A person is pushing a wheelbarrow along a ramp that makes an angle α = 31.0° with the horizontal. The wheelbarrow and load have a combined mass of 21.10 kg with the center of mass at the midpoint of the length L. What is the total force the person must apply so that the wheelbarrow remains horizontal on that ramp? Number 126.38 here is a hint available! A person is pushing a wheelbarrow along a ramp that makes an angle...

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...
In the wheelbarrow above, the load has a perpendicular lever arm of 9 cm, while the hands have a perpendicular lever arm of 0.97 m. (a) What upward force must you exert to support the wheelbarrow and its load if their combined mass is 58.5 kg? (b) What force does the wheelbarrow exert on the ground?
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...

A seesaw consisting of a uniform board of mass and length supports at rest a father and daughter with masses my and respectively, as shown in the figure. The support (called the futrum) is under the center of gravity of the board, the father is a distance from the center, and the daughter is a distance from the center A balanced system ME (a) Determine the magnitude of the upward forcen exerted by the support on the board SOLUTION Conceptualize...
electromagnetic fields theory If a load with a mass of m Ig is placed on the loop as shown in Figure 2, investigate the required length of 1 in order to make the load levitates while keeping (ii) the distance of the load to the infinite wire at 2.1 cm distance shown in (the same Figure 2). Then, suggest a method that can effectively reduce the length of l. Given that the gravity acceleration is g 9.8 m/s2. 15 Marks]...
Figure 1 describes a crane that has a mass of 1 tonne, a centre of gravity at point G and lifts a load (F) of 10791 N. The supports are a journal bearing at point A and a thrust bearing at point B. a) Is this a statically indeterminate structure and explain why or why not? b) Find all the reactions that you can.
