Simple Machine questions from picture:
For your picture: a) describe Din Dout Fin Fout b) Determine Mechanical Advantage c) answer
additional questions about your picture.
17) You have picture A. additional question: If the weight is 700 Newtons, what force must
you pull down to lift it.
18) You have picture B. additional question: If you pull up a distance of 50cm, how high does
the object move
19) You have picture C. additional question: If you pull down with a force of 10Newtons,
what is the weight of the object.
20) You have picture D. additional question: If you want the weight to move up 40cm, how
much must you pull up.
21) You have picture E. additional question: If the weight is 600 Newtons, what force must
you pull down to lift it?
22) You have picture F. The plank is 200cm & the height is 50cm. additional question: If the
weight of the cart is 250 Newtons, what is your pulling force?
23) You have picture F. Length of plank is 150cm & the height is 30cm. additional question:
What must be the weight of the cart if it took 100 Newtons to pull it up the ramp.
24) You have picture G. The weight of the rock is 1000 Newtons and your lifting force is 50
Newtons. Additional question: How much will the rock be lifted if you pushed down 120 cm.
25) You have picture G. Distance you push down is 80cm and rock is lifted 10cm. Additional
question: What is the weight of the rock if you pushed down with a force of 200 Newtons.
26) You have picture H. The ramp length is 250cm and the height is 100cm. Additional
question: What is the weight of the load if you pushed it up with a force of 350 Newtons.
27) You have picture H. The weight of the load is 2000 Newtons & you pushed it up with a
force of 200 Newtons. Additional question: What must be the length of the ramp if you
pushed it up to a height of 150cm.
28) You have picture I. The weight of the load is 900 Newtons and the force of one turn is 30
Newtons. The circumference of one turn is 150cm. Addiitonal question: How many turns
must you do to raise the weight 1000cm.
