A hand truck and its load, as shown below, have a mass of 100kg, and their centre of gravity (together) is at point C. What force F must the delivery person exert at the handles A of the hand truck to move it up the hill? Hint: In what direction is the force at the axle? Bonus question: How could the delivery person reduce the magnitude of the force they must exert?

The platform scale consists of a combination of third and first class levers so that the load on one lever becomes the effort that moves the next lever. Through this arrangement, a small weight can balance a massive object. If a 3kg counterweight S is used to balance a 120kg load L, what is the value of 'x'? Draw all pertinent FBDs. Use g=9.806 m/s2.

Block 1 (19 kg) is setting on the floor of an elevator. A rope pulls vertically up on block 1 with a tension of 10 N. The elevator is moving downward with a decreasing speed and the magnitude of the acceleration is 2 m/s2.On a sheet of paper, draw the free body diagram for block 1 using the two-subscript notation from class. After completing the free body diagram, enter below each force and its x & y-components. Remember that the x-component is the "i" component and the y-component is the "j" component.

11. A beaker of water sits on a balance. A metal block with a mass of 70 g is held suspended in the water by a spring scale in position 1, as shown. In this position, the reading on the balance is 1260 g, and the spring scale reads 120 g. When the block is lifted from the water to position 2, what are the readings on the balance and spring scale? Balance reading Spring scale reading 1190 g 1190 g 1260 g 1330 g 120 g (A) (В) (C) (D) 190 g 120 g 120 g
The diameters of a small piston and a large piston of hydraulic jack are 2 cm and 10 cm respectively. A force of 60 N is applied in the small piston.

If the mass of the hanging-mass is increased and the mass of the cart remains the same, how would the steepness of the position versus t2 be affected? The best-fit line would decrease in steepness.The best-fit line would increase in steepness. Impossible to determine because the net force is not a part of the position vs t2 graph.There would be no change in steepness.
