Answer:
B
Explanation:
A robot's work envelope is its range of movement. It is the shape created when a manipulator reaches forward, backward, up and down. These distances are determined by the length of a robot's arm and the design of its axes. ... A robot can only perform within the confines of this work envelope.
Answer:
E=2 G(1+2μ)
Explanation:
Isotropic material :
Those material have same property in all direction is known as isotropic material.
Homogeneous material :
Those material have same property through out the volume is known as homogeneous material.
Relationship between Poisson ratio ,young modulus and shear modulus:
E=2 G(1+2μ)
Relationship between Poisson ratio ,bulk modulus and shear modulus:
E=2 K(1-μ)
Where
E is young modulus.
G is shear modulus.
μ is Poisson ratio.
Earth rotates every day for a full rotation of 24hours
Answer:
It would decrease the SRT
Explanation:
The SRT is the average time it will take for the activated-sludge solids system to decompose. The concept is expressed in days. The retention time is a very important design and operational parameter in the design of an activated sludge digester. The make-up stream from the second clarifier contains a considerable amount of bacteria which are already active. Therefore, the synergistic action of the bacteria makes the sludge to be digested faster. This, In turn, reduces the time it takes to digest the sludge. Thus, the make-up stream lowers the retention time.
PPE is equipment that will protect workers against health or safety risks on the job. Explanation: The purpose is to reduce employee exposure to hazards when engineering and administrative controls are not feasible or effective to reduce these risks to acceptable levels.
