Question 1

Consider the following statements in connection with the phase diagrams
[1]. Phase diagrams of binary alloys change by the presence of other alloying elements.
[2]. Tie-line construction and lever rule are used to determine the phase compositions.
[3]. Time-temperature transformations can be studied with the help of phase diagrams.
Which of the above statements are correct?

Question 2

A ball of weight 100 N is tied to a smooth wall by a cord making an angle of 30 ° to the wall.
The tension is the cord is :

Question 3

Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:

Statement (I): Cams used in high-speed application should have displacement, velocity and acceleration curves of the follower in continuity.
Statement (II): Abrupt changes in these curves will cause high contact stresses at the bearings and make the operation noisy.

Question 4

Uniform heat generation takes place in a symmetric slab so that heat flows towards both sides in contact with fluid. The zero-grsdient boundary condition

occurs at

Question 5

Consider the following statements:
1). A system-oriented approach
2). A multidiscipline team approach
3). A function-oriented approach
Which of the above refer to value engineering?

Question 6

Assertion (A): The centrifugal tension in a belt is T_C = mV²_.
Reason (R): Since this expression is independent of the cross- section, it follower that T_c is independent of the belt size.

Question 7

Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:

Statement (I): Composite material is combination of two or more chemically unlike materials.
Statement (II): Composite materials have their own specific properties and are different from their individual material properties.

Question 8

Which among the following Robot Reference Frames represents Joint Reference?

Question 9

Question 10

At a section of a beam, shear force is F with zero BM. The cross-section is square with a side ’a’. Point A lies on the neutral axis and point B is mid-way between neutral and top edge, i.e. at distance a/4 above the neutral axis. If $Description: F:\GradeStack Courses\GATE Tests (Sent by Ravi)\GATE-22-April\GATE-IES-ME-Strength-of-Materials_files\image280.png$ and $Description: F:\GradeStack Courses\GATE Tests (Sent by Ravi)\GATE-22-April\GATE-IES-ME-Strength-of-Materials_files\image281.png$ denote shear stresses at points A and B, then what is value of $Description: F:\GradeStack Courses\GATE Tests (Sent by Ravi)\GATE-22-April\GATE-IES-ME-Strength-of-Materials_files\image280.png$ / $Description: F:\GradeStack Courses\GATE Tests (Sent by Ravi)\GATE-22-April\GATE-IES-ME-Strength-of-Materials_files\image281.png$ ?

Question 11

Consider two shafts connected with two gears as per the following options :
1) One on each shaft.
2) Through an intermediate gear mounted on an intermediate shaft, and every shaft having one gear only.
3) Through an intermediate gear mounted on an intermediate shaft having two gears, whereas the other shafts have one gear Each
Which of the above represent(s) a simple gear train?

Consider the following statements regarding composite materials:
[1]. Material is termed as advanced composite, if fibres are directionally oriented and continuous.
[2]. Reinforced fibre glass products are strong and light weight.
[3]. Concrete is reinforced with steel rebar, the rebar becomes matrix.
[4]. Pearlitic steels are composite materials.
Which of these statements are correct?
