A meter rule is anchored at the point O and is free to rotate about an axis passing through O and perpendicular to the plane of the meter rule. Forces F1, F2, F3, F4 and F5 of equal magnitudes act on the ruler at different locations. The magnitude of each force is 18.0 N and € =30º. The distances along the ruler are given in cm. Assume all quantities are correct to 3 significant figures. O F₁₁ 30 0 F₂ 60 F₁ 100 F5
A garage door is mounted on an overhead rail as shown below. The wheels at A and B have rusted so that they do not roll, but rather slide along the track. The coefficient of kinetic friction is 0.50. The distance between the wheels is 2.00 m, and each are 0.50 from the vertical sides of the door. The door is uniform and weighs 977 N. It is pushed to the left at constant speed by an external horizontal force. If the distance h is 1.54 m: a. What is the vertical component of the force exerted on the wheel A by the track? b. What is the vertical component of the force exerted on the wheel B by the track? c. Find the maximum value h can have without causing one wheel to leave the track. A В K 2.00 m h k- 3.00 m Figure 3.

A person pushing a uniformly-loaded 30.2 kg wheelbarrow of length L with pushing force P is attempting to get it over a step. The maximum horizontal force that the person can apply is Px = 553 N. What is the maximum height h of the step, expressed as a fraction n of the wheel's radius R, that the person can get the wheelbarrow over? The gravitational acceleration is g = 9.81 m/s². 10 P L R h = nR h = R
A child’s toy consists of a small wedge that has an acute angle of 34◦. The sloping side of the wedge is frictionless, and the wedge is spun at a constant speed by rotating a rod that is firmly attached to it at one end. When the mass of 41 g rises up the wedge a distance 46 cm and stays there, what is the speed of the mass? The acceleration of gravity is 9.8 m/s2 .
In the figure below, block 2 of mass m2 = 3.75 kg rests on a frictionless surface. It is attached %3D to mass 1 (m1 = 2.50 kg) by a massless, stretchless string that passes over a frictionless pulley %3D of radius R = 15.0 cm. When released from rest, block 2 moves to the right with an acceleration of 3.80 m/s2. What is the mass of the pulley? (Note: you must draw FBDS and show all work to get full credit.) T
A brick of mass 1.19 kg is attached to a thin (massless) cable and whirled around in a circle in a vertical plane. The circle has a radius of 1.34 m. The cable will break if the tension exceeds 45.0 Newtons. What is the maximum speed the brick can have at the bottom of the circle before the cable will break?
m1 = 20 kg, determine the mass of m2 which will cause the system to stay in equilibrium. The pulley does nothing other than change the direction of the force from the hanging mass.
One end of a string is wrapped several times around a pulley of mass 0.92 kgkg that is oriented vertically. The other end of the string is connected to a block of mass 0.35 kg, which is then slowly lowered until the string becomes taut. After which the person lets go of the block completely, thus allowing the block to descend and the pulley to rotate in unison. What is the magnitude of the acceleration of the block after the person has let go?
