Number of drill blows per minute. hope this helps !!
Answer:
1. 3.75
2. 1.39 ft
Explanation:
The mechanical advantage is the ratio of the resistance force to the effort force.
MA = 75 lb / 20 lb
MA = 3.75
The sum of the torques about the fulcrum equals zero.
∑τ = Iα
(20 lb) (5.2 ft) − (75 lb) x = 0
x = 1.39 ft
Round as needed.
Answer:
7 bits
Explanation:
Given
Instruction Set = 110 operation
Memory unit = 32 bits per word.
We get the required bits by using the following formula
2^n = 110
But 110 is not a factor of 2.
So, we pick the nearest decimal number greater than 110 that is a power of 2.
The number is 128
2^n = 110 becomes
2^n = 128
2^n = 2^7 ---- 2 cancels out
So,
n = 7
Hence, the required number of bits needed for the opcode is 7 bits
