(a)
The unknown value
Answer to Problem 16A
Speed of gear B is
Speed of gear C is
Speed of gear D is
Explanation of Solution
Given information:
A gear and pinion arrangement is given as below.
Calculation:
We have been given below information,
As we know that in a gear arrangement,
So,
Hence, speed of gear B is
Since, gear B and C are on same shaft. So, speed of both gear is equal.
Therefore, speed of gear C is
Again,
Hence, speed of gear D is
Thus, speed of gear B is
Speed of gear C is
Speed of gear D is
(b)
The unknown value
Answer to Problem 16A
Number of teeth in gear B is
Number of teeth in gear D is
Speed of gear C is
Explanation of Solution
Given information:
A gear and pinion arrangement is given as below.
Calculation:
We have been given below information,
As we know that in a gear arrangement,
So,
Hence, number of teeth in gear B is
Since, gear B and C are on same shaft. So, speed of both gear is equal.
Therefore, speed of gear C is
Again,
Hence, number of teeth in gear D is
Thus, number of teeth in gear B is
Number of teeth in gear D is
Speed of gear C is
(c)
The unknown value
Answer to Problem 16A
Number of teeth in gear A is
Speed of gear B is
Speed of gear C is
Explanation of Solution
Given information:
A gear and pinion arrangement is given as below.
Calculation:
We have been given below information,
As we know that in a gear arrangement,
So,
Since, gear B and C are on same shaft. So, speed of both gear is equal. i.e.
Again,
Hence, speed of gear B and gear C is
Putting,
Thus, number of teeth in gear A is
Speed of gear B is
Speed of gear C is
(d)

- Of two gears that mesh, the one that has the greater number of teeth is called the gear, and the one that has the fewer teeth is called the pinion (Figure 218). For each of the problems, set up a proportion, and determine the unknown value, x. Round the answers to 1 decimal place where necessary.arrow_forwardIn Figure 208, gear A is turning at 120 revolutions per minute and gear B is turning at 3.6 revolutions per second. Determine the ratio of the speed of gear A to the speed of gear B.arrow_forwardA double-threaded square-thread screw is shown in Figure 5-7. The pitch of a screw is the distance from the top of one thread to the same point on the top of the next thread. The lead is the distance the screw advances for each complete turn or revolution of the screw. In a double-threaded screw, the lead is twice the pitch. Given the number of turns and the amount of screw advance, determine the lead and pitch.arrow_forward
- A single-threaded (or single-start) square-thread screw is shown in Figure 5-6. The lead of a screw is the distance that the screw advances in one turn (revolution). The lead is equal to the pitch in a single-threaded screw. Given the number of turns and the amount of screw advance, determine the leads.arrow_forwardFive holes are drilled in a steel plate on a bolt circle as shown in Figure 43-9. There are 300( between hole 1 and hole 5. The number of degrees between any two consecutive holes doubles in going from hole 1 to hole 5. Find the number of degrees between the indicated holes. a. 1 and2 b. 2 and 3 c. 3 and 4 d. 4 and 5arrow_forwardA micrometer reading is made at dimension D on a tapered shaft (Figure 217). For each of the problems use the dimensions given in the table, compute the taper, set up a proportion, and determine diameter C to 3 decimal places.arrow_forward
